Description

This example shows how the ESL can be applied in the ultimate strength structural analysis in Abaqus finite element software. In other words, ESL methodology is applied only in some parts of the structure while larger structural supporting components like girders and webframes are still modeled explicitly. FIles include also the Full_3D_FEM model used for validating the ESL model.

Dataset includes following files:

1. ESL_nonlinear_grillage.inp - this is Abaqus input file for running the ESL nonlinear grillage model.

2. ugensFINALv_master.for - this defines the nonlinear stiffness or ABD matrix. This is called by input file (ESL_nonlinear_grillage.inp ).

3. Full_3D_FEM.inp -  Full_3D_FEM model used for validating the ESL model.
