Yu Zheng — Computational mechanics. Impact dynamics, material models, and scientific software.

I work on computational mechanics, with a focus on impact dynamics, constitutive modeling, and material failure. I'm also exploring differentiable simulation for material characterization and inverse problems.

I contribute to open-source scientific software for computational mechanics.
