Trouble with linear elastic theory of strength

Submitted by Zhigang Suo on

A body is subject to a load. What is the magnitude of the load that will cause the body to fracture? Let us begin with a body made of a glass, which deforms elastically by small strains. A procedure you have been taught before probably goes as follows. You first determine the maximum stress in the body. You then determine the strength of the material. The body is supposed to fracture when the maximum stress in the body reaches the strength of the material.

Critical Experimental and Theoretical Tests for Failure Criteria

Submitted by Richard M. Chr… on

 A new section has been added to the website http://www.failurecriteria.com/.  This is on critical tests for failure criteria.  It summarizes most of the previous entries to the website and provides evaluations of the most salient of the failure criteria by comparing with high quality experimental data.

Stability/Buckling analysis vs Geometric non-linearity

Submitted by bruno-page on

Can anyone point out some important conceptual differences between a non-linear analysis incorporating geometric-non linearity (be it using Total Lagrangian/Updated Lagrangian/ co-rotational formulation) and a stability (buckling) analysis.

Sorry for asking too fundmantal question
