Finite Element Implementation of Damage Models for Composite Structures

Žmindák M., Riecky D., Danišovič S.

Machine Dynamics Research

2010

Vol. 34, No. 4

130-138

This paper presents numerical modelling of composite damage by finite element method (FEM). The damage model is implemented it in ANSYS software for a one dimensional bar element. A return mapping algorithm integration is implemented in conjunction with plane stress element PLANE182. These subroutines should be linked with the ANSYS program beforehand.

Neural procedures for the hybrid FEM/NN analysis of elastoplatic plates

Kaczmarczyk Ł., Waszczyszyn Z.

Vol. 12, No. 4

379-391

A neural procedure was formulated in [4] as BPNN (Back-Propagation Neural Networks) for the simulation of generalized RMA (Return Mapping Algorithm). This procedure was evaluated to be too large to make a corresponding hybrid FEM/BPNN numerically efficient. That is why two new procedures NPI and NP2 were formulated. A description of their efficiency is presented in the paper, related to the computation number of computer operations and CPU time, carried out by FEM program FEAP and two hybrid programs FEAP/NP1 and FEAP/NP2.
