The effect of material property gradient on the fracture toughness of a PMMA/PC bimaterial with a crack normal to the interface

The effect of material property gradient on the fracture toughness of a PMMA/PC bimaterial with a crack normal to the interface

Fracture toughness tests on CT specimens were carried out to study the fracture behavior for a crack lying perpendicular to the interface in a PMMA/PC bimaterial. Polymethylmethacrylate Acrylic (PMMA) and Polycarbonate (PC) cylindrical rods were joined together using the friction welding process....
