Multiscale Mesh-based Meshless Method M4
Abstract
Abstract The primary objective of the proposed Multiscale Mesh-based Meshless Method M4 approach is to develop a predictive simulation framework for analysis of soda lime glass subjected to extreme pressure and loading rates including phase transformation with up to 80% volume change. Our first goal (Task 1) would be to reproduce the physical phenomena of phase transformation processes, by carrying out comprehensive atomic scale simulation of fused silica under combined pressure/shear loading conditions using appropriate potentials. Once we are successful at this task, we will explore various coarse-graining procedures (Task 2) as described in Sections 3 and 4 to make the methodology applicable at the continuum level where it can be implemented as UMAT in ABAQUS or LS DYNA. We expect the first two tasks to be completed in two years, one year for each task. Once we are able to reproduce and coarse grain the physical phenomena at a molecular level, the third year will be devoted to continuum representation (Task 3) of physics captured at a molecular and coarse-grained scale. In the remaining of this proposal, we will describe, the state-of-the-art in this field (Section 1), the rationale behind the need of M4 (Section 2), how M4 is formulated (Section 3), what related applications of M4 are (Section 4).
