Crystal defects - stress and strain
7 important questions on Crystal defects - stress and strain
Difference true stress-strain curve and engineering stress-strain curves
Some linear elastic materials and some non-linear elastic materials
nonlinear=concrete, cast iron, rubber, natural rocks, PVC
Volume expansion materials with poissons ratio under 0.5
is final volume
V0 is Original volume
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Yield point linear elastic materials
Elastic recovery linear elastic material
Finding yield point non-linear elastic metals
Hall Petch relationship
is yield stress (MPa)
is a material specific constant (related to stress needed for dislocation movement MPa)
is the material specific constant (MPa)
d is the average grain diameter (m)
