(a) Determine the cohesive strength of alumina whisker (E = 500 GPa) (b) Assuming that fracture o...
What is the theoretical fracture strength of a brittle material if fracture occurs by the propagation of a surface crack 1.0 mm deep and with a tip radius of curvature of 0.01 mm when a stress of 5.0 GPa is applied?
recrystallization? During grain growth? o How is the material strength affected during r o What happens on a microstructural level during cold vw ecte amncrusuecire during recovery? During ecovery? During recrystallization? During grain growth? As you read through the sections of Ch. 8, consider the following questions: o What are the similarities & differences between ductile and brittle fracture? o What are the similarities & differences between transgranular and intergranular fracture? o How do cracks cause materials to be weaker...
