I am trying to simulate a seismic earthquake analysis in order to study collapse pattern on LS DYNA.


I have build the keyword from scratch.Although, I am new to LS Dyna, I have never performed such a simulation, I have build a test model consisting of 2 columns joined by a beam resting on a finite element representing soil.

Hello, researchers. I have difficulty in understanding the physical meaning of Green-Lagrangian strain (E) and Eulerian-Almansi strain (A) measures. Mathematically speaking, I can derive the equations of these strains in different ways. But physically speaking, it's a bit harder to understand how these strains (E and A) can be pictured and how to give a proper physical definition for them. In a simple case, considering a uni-axial bar (Please refer the attached file), Engineering strain can be understood easily, but in E and A equations, from where do the squares of the lengths originate?
