STRENGTH OF MATERIALS 1 BLACKWATCH ENGR. PAUL L. LADESMA Civil Engineer | Materials Engineer 1 | Provisional Project Engineer An occurrence in a ductile material which allows it to be stressed considerably beyond the yield point without failure. A. Failure free tension B. Pre-stressing C. Ductility D. Strain Hardening SOLUTION: Strain Hardening - Strain hardening refers to the process of material hardening through deformation, which occurs due to the interaction and multiplication of dislocations during plastic deformation. Answer = Strain Hardening
STRENGTH OF MATERIALS 1 BLACKWATCH ENGR. PAUL L. LADESMA Civil Engineer | Materials Engineer 1 | Provisional Project Engineer The gradual deformation of a material over time under constant stress, often at high temperatures A. Fatigue B. Strain Hardening C. Creep D. Resilience SOLUTION: Creep is the gradual deformation of a material over time under constant stress, often at high temperatures. It's a slow, permanent change in shape that occurs when a material is subjected to a constant load or stress, even if the stress is below the material's yield strength. Answer = Creep
