Numerical Study of the Behavior of Two-Dimensional Materials with Microstructure Bistability, M.Sc. Thesis Sharif University of Technology ; Arghavani Hadi, Jamal (Supervisor)
Abstract
In the present study, the energy absorption mechanism is presented that used in two-dimensional microstructures. By studying the angular geometric parameters and the narrow ratio of the tilted members, we can use the property of the geometry of the structure to be bistable. In this way, there can be two stable geometries with different energies, which enters energy into the structure, such as the phase transformation to the second geometry that has more energy. By changing the geometric parameters, the deformed state can be stable or unstable. Because of the complex geometries that exist in this mechanism, additive production methods are more effective than geometric ratios or sharp points...
