FEA, THAT NEEDS TO UNDERSTAND...

 Hey guys, Today we are going to talk about meshing, I know another meshing one blog yes... I know we already discuss some meshing concept but today we are exploring it a bit more... so let's start  We know why we carry out meshing and what its advantages also we had discussed about the DOF and nodes, elements blah blah... if you don't read it I am providing the link here check it out https://understandingfea.blogspot.com/2020/10/meshing-fem-and-types-of-elements.html So the basic purpose to carry out is to make calculations at finite points. We know that we have to carry out meshing for the various geometries and geometry can be different and complex.                     Then what to do in such cases, Lets explore it we know that our FEA problem which we are solving is needed to be easy and not very much complex and, if you have a complex problem then we need to identify how can we simplify it... We can simplify the ...

 Hey guys Today we are talking about the most important topic i.e. the nonlinearity of FEA.  What is non-lineaities? We have talked about linear and non-linear analysis. And how they differentiate from each other. Every problem that we encountered in real life is non-linear. But for the sake of simplifying the problem, we do it with the linear analysis.  What is the linear analysis means? In which for solving any type of problem we considered that the force and the displacement (As an output) are changing linearly. As in the linear analysis the stiffness of matrix doest change it remains constant.                As in the non-linear analysis, there are different types of non-linear analysis. The nonlinearities vary or it depends on various factors there are various types of non-linearites such as a 1) Material nonlinearity 2) Geometric nonlinearity 3) Contact nonlinearity   1) Material nonlinearity As in Material nonlinear...

 Hey guys, Let's look at the Introduction to FEA. To solve the analysis we are going from basics that describes the FEA theory. It is just like the book...but I try to explain it in simple language. I will try my best. So let's go through it... So, to solve any engineering problem there are three approaches  1.Analytical Approach  2.numerical Approach 3.Experimental Approach 1.  Analytical Approach  The Analytical Approach is the theoretical approach or the classic approach. Which has a 100% accurate result.  It is like the paper pen method. This is a classic approach that is used early in the 19s. The analytical approach is only can be used for like the simple problems like the cantilever beams and the simply supported beam. The analytical approach or method can give an approximate result if the solution is closed form but in the broad sense, the method is known as closed-form solution i.e. 100% accurate. There are two steps to solve the method. Step 1: Wr...
