报告题目：Topological Design for Novel Pentamode Mechanical Metamaterials
Abstract: Pentamode metamaterials are a new class of three-dimensional mechanical metamaterials, artificially engineered to have unusual elastic property: a very large but realistically attainable ratio of the effective bulk modulus compared to its shear modulus, mimicking the behaviour of fluids but are solid, hard to compress yet easy to deform. This research is motivated to use topological optimization method for finding novel pentamode architectures through the overall elastic deformation of isotropic microstructures, not the double-cone rigid bodies dominantly used by most up-to-date design philosophies.
