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 talk about the meshing of FEA, FEM, and its types. That is really an important concept of FEA that every FEA analyst needs to know.                 The basic theme for the generation of mesh is to make the calculation at the finite no of point and then interpolate the result at the entire surface and domain.  For example the above dig. shows that if we have a surface and want to calculate the result then we cant calculate it bcoz of where in the domain having an infinite no of points and each point having 6 dof so the total equation created is infinite. In another way in dig 2 we are dividing the domain in some finite no of points and the equation generated is 48.               The Finite Element Method reduces dof from an infinite no of points to a finite no of points with the help of discretization i.e. meshing (Nodes & Elements) All calculation made at nodes and th...
