Conducting research on the following areas: 1) Advanced discretizations and numerical methods for PDEs (such as Virtual Element Method (VEM) and polygonal finite element method), with special interests in mechanics problems involving nonlinear material behavior and finite deformations. 2) Single- and multiple- material topology optimization of nonlinear elastic materials. 3) Material microstructure design optimization considering multi-physics, such as electrical-mechanical coupling. 4) Additive manufacturing material microstructure and soft materials
Collaborating on: (1) propose a 3D topology optimization formulation on arbitrary polyhedral meshes using the Virtual Element Method (VEM). (2) developed a robust 3D polyhedral meshing tool in Matlab that generates high-quality polyhedral meshes for both Cartesian and non-Cartesian domains.
Assisted teaching for the following courses: 1) CEE570: Finite Element Methods 2) CEE470: Structural Analysis 3) CEE 360: Structural Engineering
1) developed displaced-based and mixed polygonal and polyhedral finite element formulations for finite elasticity 2) developed a variational theory and its computational algorithm that can efficiently and effectively model rigid inclusions of arbitrary shape embedded in elastomeric matrices in 2D and 3D when subjected to finite deformation.
1) Developed finite element models in FORTRAN for simulating the deformation fields in excavated slopes using the Duncan-Chang constitutive model. 2) Implemented the back-propagation (BP) Neural Network model in FORTRAN and trained the BP Neural Network to predict the deformation of excavated slopes based on extensive data from finite element simulations.
