of associated elastic follow-up (EFU). However, although there is a significant body of work related to the influence of EFU on the high temperature creep behaviour of uncracked structures, the EFU concept has not yet been rigorously applied to the fracture...

A series of experiments were undertaken using a multiple bar assembly to measure elastic follow-up and relaxation of an initial residual stress. A test rig was designed to permit different levels of elastic follow-up to occur. The general features...

Based on the traditional definitions associated with creep strain accumulation in defect free components, a generalised definition for “elastic follow-up” factor, Z is proposed that characterises the impact of a “nonlinear” event experienced locally...

This paper reviews the concepts and definitions related to elastic follow-up, Z, together with its potential use in stress classification. Based on the principles governing benchmark multiple bar structures elastic follow-up (EFU) is quantified...

A unified framework for quantification of elastic follow-up is provided by using simplified benchmark models that ideally represent the behaviour of real structures. Closed form analytical solutions for evaluation of EFU are presented for model...

Using simplified benchmark models, representative of the behavior of real structures, a

unified framework for quantification of elastic follow-up (EFU) in structures has been provided.

Closed form analytical solutions for evaluation...

, constitutive equations or the

elastic regions around the nonlinear events have an effect on the rate of strain accumulation. The elastic follow-up can explain the mechanism of plastic strain accumulation.

This phenomenon may occur when a...
