What is FEA? Why FEA? What do you get from FEA?….

What is FEA....
When the Finite Element Method (FEM) is applied to a specific field of analysis (like stress analysis, thermal analysis, or vibration analysis) it is often referred to as Finite Element Analysis (FEA).
 
Why FEA....
FEA consists of a computer model of a material or design that is stressed and analyzed for specific results. It is used to verify a proposed design that  will be able to perform to the client's specifications prior to manufacturing or construction. 
 
 In case of structural failure, FEA may be used to help determine the design modifications to meet the new condition. 
 
Part of Engineering Design process which  takes preliminary design as input and gives final design as output 
 
Analysis deals with different parameters like deflection, strain, stress, stiffness, natural  frequencies, mode shapes, temperature distribution, temperature gradients, heat flux,etc. 
 
We can get detailed visualization of where structures bend or twist, and the distribution of stresses and displacements, etc.

  1. I was depressed when doctor told me that I have been diagnosed with Herpes disease… I thought about my Family, I know my Family will face a serious problem when I'm gone, I lost hope and I wept all day, but one day I was searching the internet I found Dr.ezomo contact number. +2349056460552   I called him and he guided me.
