In continuum damage models involving strain softening, various Quantities of Interest (QoIs) such as energy dissipation are pathologically dependent on the discretization resolution (i.e. mesh size). For finite element methods, this is referred to as the mesh size sensitivity, implying lack of regularization. The…
Intergranular and transgranular fracture play a critical role in determining the fracture behavior and toughness of polycrystalline materials, such as metals and ceramics. These mechanisms are strongly governed by microstructural features, including grain size, grain shape, crystallographic orientations, and grain boundary properties. We present…
A 17 µm diameter UHMWPE fiber consists of over 100,000 fibrils with diameters ranging from 10 to 100 nm. These fibrils can exhibit various relative rotations around the axial direction, forming interphases between distinct crystal planes. Fiber failure often occurs through defibrillation, determined by…
