Engineering stress is the ratio of the load and the undeformed original cross-sectional area. Engineering stress approximates strain which represents the ...
قانون هوك
قانون هوك
Hooke's law states that stress applied to a material is directly proportional to the strain it experiences within the elastic limit. For ductile ...
