Cyclic effects and recrystallisation in temperature and rate dependent state variable based plasticity

Author: Jansen van Rensburg, Gerhardus J ; Kok, S ; Wilke, DN Date: Oct 2016 A constitutive model that captures the dominant strengthening and softening physics or microstructural changes of metallic materials is needed within a numerical environment for the effective prediction and simulation of plasticity during hot ...

Development and implementation of state variable based user materials in computational plasticity

Author: Jansen van Rensburg, Gerhardus J Date: Sep 2016 The Finite Element Method is a powerful tool that can be used to test, improve or better understand an industrially relevant problem. There are numerous Finite Element Analysis (FEA) software packages that operate either in the commercial, ... Read more
Material parameter identification on metal matrix composites

Author: Jansen van Rensburg, Gerhardus J ; Kok, S ; Wilke, DN Date: Jul 2012 Tests were done on the compressive behaviour of different metal matrix composite materials. These extremely hard engineering materials consist of ceramic particles embedded in a metal alloy binder. Due to the high stiffness and brittle nature ... Read more
Numerical simulation of plastic deformation and mechanical response of strip rolled aluminium alloys

Author: Jansen van Rensburg, Gerhardus J ; Bogaers, Alfred EJ Date: Oct 2018 During the optimal design and simulation of machining or forming processes, detailed simulation of structural response is typically required for use in Finite Element Analysis (FEA). In this study, the bulk temperature and rate dependent ... Read more
