Abstract: 

Assessment of strain accumulation due to nonlinear events like creep, plasticity or ratchetingphenomenon has gained importance, as it causes an increase in creep and fatigue damage of materials.
Some factors like the magnitude of loading, constitutive equations or the elastic regions around thenonlinear events have an effect on the rate of strain accumulation. The elastic follow-up can explain themechanism of strain accumulation. This phenomenon may occur when a mechanical structure withelastic manner is connected to non-linear events and they are subjected to a displacement load. In thesecases, the high rigidity portion of elastic region of mechanical structure may enhance the force to theregions with low rigidity. So in the local non-linear portion, the strain is accumulated. This phenomenonis proposed as an important instruction in mechanical assessment codes. In this study, the effects ofElastic Follow-up phenomenon on strain accumulation due to elastic-plastic and local creep areinvestigated. So the Elastic Follow-up parameter is defined by the methods which are described in hightemperature assessment procedures (R5). The results revealed that the strain accumulation depends onthe elastic region in structures which is described by the Elastic Follow-up phenomenon.
