The Generalized Local Stress Strain (GLOSS) Analysis—Theory and Applications

Abstract

GLOSS analysis is a simple and systematic method for carrying out inelastic evaluations of mechanical components and structures on the basis of two linear elastic finite element analyses. The underlying theory relates redistribution of inelastic stresses at a given location under consideration to the uniaxial stress relaxation process. GLOSS analysis is emerging as a useful technique for determining multiaxial stress relaxation, follow-up, creep damage, inelastic strain concentrations and low-cycle fatigue estimates, limit analysis and issues pertaining to stress-classification.

A pseudo-elastic local meshless method for analysis of material nonlinear problems in solids

“…Owen and Hinton [26] provided finite element computer implementation of elasto-plastic problems based on incremental theory. Seshadri [27] developed a GLOSS method based on two-linear elastic finite element analysis which is used to evaluate the approximate plastic strains at certain local regions. Babu and Iyer [28] developed a robust method using relaxation method, which is based on GLOSS method of analysis, and an attempt was made to satisfy force equilibrium in the plastic range.…”

Linear matching method on the evaluation of plastic and creep behaviours for bodies subjected to cyclic thermal and mechanical loading

“…The operating lifetime of components subjected to cyclic thermal and mechanical loading is normally limited by the mechanisms of low-cycle fatigue, creep/fatigue interaction and excessive plastic deformation [1,2]. The evaluation of creep/fatigue interaction and other failure mechanisms of structures with variable repeated loading is a significant problem and has attracted the attentions of many researchers [3][4][5][6][7][8][9].…”

Mechanically fastened joints in composite laminates: Evaluation of load bearing capacity

“…And, in facts, in 1991 Seshadri and co-workers proposed a procedure for approximate estimates of limit load using the reduced modulus method (see e.g. Seshadri and Fernando [51], Seshadri [50]). The ECM hereafter employed refers to the paper of Mackenzie and Boyle [36] and to begin with a brief survey of the way it acts is given next.…”
