Finite Element Analysis of Impression Creep on P91

Abstract Impression creep is a versatile technique that used nowadays for studying the deformation of different materials and there no tertiary stage in this method; it's non-destructive process. The present work deals with finite element analysis plastic corresponding to impression P91 steel. In FE model, 3D deformable body as specimen along rigid hollow cylindrical indenter 0.07 fillet. effect sizes was studied, diameter changed from 10mm,15mm, 20mm whereas 1mm,1.5mm, 2mm respectively. Moreover, it found when punch increased induced stress reduced. It observed on specimen, however, 1mm 1.5mm 2mm, reduced by approximately 10% 20%, simulation run 100 hours. Furthermore, optimum distance between two impressions steel studied indenters altered 10mm,8mm,6mm 4mm respectively same loading boundary conditions, mesh size. contact deformations at 4mm.For we can perform tests apart.
