Royi Padan is a Ph.D. candidate in the mechanical engineering school of Tel-Aviv University. His research proposal relates to the “formulation of a PHFGMC micromechanical model for thermo-mechanical behavior of ceramic matrix composites”. He proposes experimental, analytical, micromechanical, and computational research carried out to model the thermomechanical behavior of ceramic composite materials (CMCs).

The proposed research aims to extend the Parametric High-Fidelity Generalized Method of Cells (PHFGMC) formulation to comprise a complete linear and nonlinear damage propagation thermomechanical temperature-dependent formulation. The extended formulation will allow the calculation of the local strain and stress field of a C/C-SiC Ceramic Matrix Composite. Thus, local single-phase damage and failure propagation can be addressed. A homogenized material mechanical degradation will be calculated and compared to continuum damage criteria developed for similar materials. 

The proposed research also expands CMC’s experimental abilities. A new approach to derive CMC’s material properties based on flat disc compressed diametrically is developed and validated. Such a method can later be used to derive the multi-stress response of a CMC orthotropic material to validate the multi-stress failure envelope derived by the proposed PHFGMC complete thermomechanical temperature-dependent model.
