Modeling & Analysis of A-Frame
A Brief History of Computer Aided Engineering
The classical period of Engineering relied on extensive testing and the development and use of fundamental principles. Galileo, Newton, Da Vinci, Hooke, and Michelangelo all contributed to the body of knowledge on mechanics and materials. Design Engineers were often asked to put their money where their mouth or pencils were. Early railroad bridge engineers often took first ride across a new structure to show confidence in their calculations. When the designer’s life was on the line, the importance of a sound understanding of the tools used was clear.
In the late 1800s Lord John William Strutt Rayleigh, known as Lord Rayleigh, developed a method for predicting the first natural frequency of simple structures. It assumed a deformed shape for a structure and then quantified this shape by minimizing the distributed energy in the structure. Walter Ritz then expanded this into a method now known as Rayleigh-Ritz method, for predicting the stress and displacement behavior of structures. The choice of assumed shape was critical to the accuracy of the results and boundary or interface condition had to be satisfied as well. Unfortunately, the method proved to be too difficult for complex shapes because the number of possible shapes increased exponentially as complexity increased, this predictive method was critical in the development of FEA algorithms in later years.

Introduction to Finite Element Analysis
A Brief History
Finite Element Analysis (FEA) was first developed in 1943 by R. Courant, who utilized the Ritz method of numerical analysis and minimization of variational calculus to obtain approximate solutions to vibration systems. Shortly thereafter, a paper published in 1956 by M. J. Turner, R. W. Clough, H. C. Martin, and L. J. Topp established a broader definition of numerical analysis. The paper centered on the "stiffness and deflection of complex structures".
By the early 70's, FEA was limited to expensive mainframe computers generally owned by the aeronautics, automotive, defense, and nuclear industries. Since the rapid decline in the cost of computers and the phenomenal increase in computing power, FEA has been developed to an incredible precision. Present day supercomputers are now able to produce accurate results for all kinds of parameters.
What is Finite Element Analysis?
FEA consists of a computer model of a material or design that is stressed and analyzed for specific results. It is used in new product design, and existing product refinement. A company is able to verify a proposed design will be able to perform to the client's specifications prior to manufacturing or construction. Modifying an existing product or structure is utilized to qualify the product or structure for a new service condition. In case of structural failure, FEA may be used to help determine the design modifications to meet the new condition.
There are generally two types of analysis that are used in industry: 2-D modeling, and 3-D modeling. While 2-D modeling conserves simplicity and allows the analysis to be run on a relatively normal computer, it tends to yield less accurate results. 3-D modeling, however, produces more accurate results while sacrificing the ability to run on all but the fastest computers effectively. Within each of these modeling schemes, the programmer can insert numerous algorithms (functions) which may make the system behave linearly or non-linearly. Linear systems are far less complex and generally do not take into account plastic deformation. Non-linear systems do account for plastic deformation, and many also are capable of testing a material all the way to fracture.

How Does Finite Element Analysis Work?
FEA uses a complex system of points called nodes which make a grid called a mesh (Figure 1). This mesh is programmed to contain the material and structural properties which define how the structure will react to certain loading conditions. Nodes are assigned at a certain density throughout the material depending on the anticipated stress levels of a particular area. Regions which will receive large amounts of stress usually have a higher node density than those which experience little or no stress. Points of interest may consist of: fracture point of previously tested material, fillets, corners, complex detail, and high stress areas. The mesh acts like a spider web in that from each node, there extends a mesh element to each of the adjacent nodes. This web of vectors is what carries the material properties to the object, creating many elements

What is the importance of Finite Element Analysis?
The awareness about Finite Element Analysis came into existence after The sinking of the Sleipner A platform on 23 Aug 1991.
The loss was caused by a failure in a cell wall, resulting in a serious crack and a leakage that the pumps were not able to cope with the wall failed as a result of a combination of a serious error in the finite element analysis which consequently lead to insufficient anchorage of the reinforcement in a critical zone.
The cell wall failure was traced to a tri cell, a triangular concrete frame placed where the cells meet, as indicated in the diagram below.
The post accident investigation traced the error to inaccurate finite element approximation of the linear elastic model of the tri cell.Due to wrong choice of element type, the shear stresses were underestimated by 47%, leading to insufficient design. In particular, certain concrete walls were not thick enough.More careful finite element analysis, made after the accident, predicted that failure would occur with this design at a depth of 62m, which matches well with the actual occurrence at 65m.

Some Basics of the Engineering Strength of Material
Engineering Stress & Strain
Engineering Stress σ is defined as applied load P divided by orginal cross sectional area A0 to which load is applied.
Stress σ = Load/Area P/ A0
Engineering Strain ε is defined as the change in length at some instant, as reference to the original length.
Strain ε = Δl/l
Hooke’s Law σ = E ε

Objective Of The Analysis On A- Frame
An analysis of an A-Frame is conducted to understand the stress and deflection that is present under product loading. Two load cases are considered to understand the structural integrity of the frame which are as follows.
1) Stress and deflection due to vertical load of 25 tons on the A-Frame being supported on the side as shown in fig.

2) Stress and deflection due to different load condition in which the A-Frame adjusted into 35 degree angle being supported on the side as shown in fig.

Actually what is A- frame?
A-Frame is commonly used in marine operations in Vessels and offshore ports for lifting heavy loads.So its construction is very typical for the safety of huge vessels and for the work force working on the ports .

Analyzing of A-Frame on Solid Works
A-frame assembly is created using 2-D & 3-D solid works. Solid and plate elements are used to create the model. A-Frame is constructed by assembling different beams (foundation A-frame, vertical beams, horizontal beam and the hook) as shown in Fig1.2. The vertical beams are supported with the help of horizontal beams. Hook is made fixed on the horizontal beam. A-Frame is used as a crane used to lift heavy loads in ships. The application of load is on the hook.
Below figure shows 2D & 3D model of A-Frame on Solid Works and information about model.

Now the above results of analysis shows the maximum stress on A-Frame due to load 25 ton which is 158872576 N/m 2
Given Yield Strength is 355000000 N/m2
Now Factor of safety can be calculated as Yield Strength/Stressmax
