ELASTO-PLASTIC STRESS ANALYSIS IN A COMPOSITE PLATE WITH A SQUARE HOLE

Öz

In this study, the elasto-plastic stress analysis of the plates with

a square hole manufactured steel-aluminum composite is made under

the uniform tension loads. In the solution, two dimensional

isoparametric rectangular element with nine nodes is used. The

automatic mesh generation is used in finite element model and the

special computer programmes are used to solve problem.

Distributions of plastic regions near the hole and variations of

residual stresses are investigated in the different oriantation angles.
