Dr Rimma Lapovok - Researcher Profile

Biography

Dr. Rimma Lapovok is the Associate Professor (Research) in Materials Engineering Department, Monash University (Australia). She has graduated in Solid Mechanics and completed her PhD in Metal Working Processes in Russia. Her scientific interests include ultrafine grained materials, modelling of plastic flow, constitutive behaviour of materials, and damage mechanics, with more than 100 publications on these topics.

 

From 1998 she works intensively in area of Severe Plastic Deformation, designing several rigs for production of ultrafine grained materials, including ECAP machine with back-pressure, High Pressure Tube Torsion, Hydro-ECAP and others. The novel approach in these processes is based on fundamentals of damage mechanics.
