Abstract

In small deformation with hot rolling process, metals and alloys are subjected to complex stresses, strain, strain-rate, stress flow, pressure, tensile triaxiality stress and compressive triaxiality stress which make it very complex to analyse. Study of damage in small deformation with hot rolling is important for manufacturing for development of defect free products. Damage is an attributed to crack and fracture during process in material. Triaxiality stress especially compressive triaxiality stress develops the tendency of fracture in material during the hot rolling process. In the present study, FE simulation of hot rolling process for small deformation has been carried out by using commercial available ABAQUS/Explicit software. Damage during the small deformation has been examined and salient conclusions are drawn.
