On Application of the Maximum Entropy Meshless Method for Large Deformation Analysis of Geotechnical Problems Nadia Zakrzewski1, a *, Majid Nazem1, b, Scott Sloan1, c and Mark Cassidy2, d Australian Research Council Centre of Excellence for Geotechnical Science and Engineering 1The University of Newcastle, Callaghan NSW 2308, Australia 2The University of Western Australia, Crawley WA 6009, Australia anadia.zakrzewski@uon.edu.au, bmajidreza.nazem@newcastle.edu.au, cscott.sloan@newcastle.edu.au, dmark.cassidy@uwa.edu.au Keywords: Large deformation, Updated Lagrangian, Maximum Entropy Meshless Method Abstract.
Complexities arise from material nonlinearity, changing boundary conditions, extremely large deformations occurring in the soil, the presence of pore water pressures and, in some cases, dynamic loading.
A static displacement analysis was performed and the behaviour of the clay layer was modelled using the Tresca material model.

Introduction Due to the high temperatures that are required for homoepitaxial growth of 4H- and 6H-SiC polytypes, the use of high-temperature masking materials was required for selective epitaxial growth (SEG) of 4H- or 6H-SiC [1,2].
