The mechanical behavior of newly developed composite materials is dependent on several underlying microstructural phenomena. In this research, a periodic 2D geometry cast X8CrMnNi16-6-6 steel and 10% zirconia virtually constructed by adopting attributes from literature. A physics-based crystal plasticity model with ductile damage criterion used for defining the austenitic matrix. particles are ...

Recent technological advancements led to active research in the field of additive manufacturing (AM) thanks its ability fabricate complex structures with reduced material waste. While many studies focused on quasi-static performance AM materials and structures, investigations dynamic these are still limited, especially for polymers composites. The aim this is investigate fracture behaviour poly...

A controlled crack growth was achieved in single edge—cracked specimens made of a high—molecular weight PNNA by regulating the cross— head speed of loading of the specimens by a computer—driven testing device. The crosshead speeds used during the tests were varied between v =1x107m/s and 1X1O5m/s. 5 It was shown that in this area of very slow quasi—static loading of brittle plexiglas specimens ...

When a cylindrical tool cuts through a thin sheet of a relatively brittle material, it leaves behind a visually arresting crack street in its wake, reminiscent of a vortex street in the wake of a cylinder moving through a fluid. We show that simple geometrical arguments based on the interplay of in-plane stretching and out-of-plane bending suffice to explain the cycloidal morphology of the curv...

CoSb3 based skutterudite thermoelectric material has superior thermoelectric properties, but the low fracture toughness prevents its widespread commercial application. To determine the origin of its brittle failure, we examined the response of shear deformation in CoSb3 along the most plausible slip system (010)/<100>, using large-scale molecular dynamics simulations. We find that the brittle f...
