190 Mechanical properties Many materials,when in service,are subjected to forces or loads The mechanical behavior of a material reflects the relationship between its response or deformation to an applied load or force. Important mechanical properties are strength, hardness,ductility,and stiffness. Usually materials are tested with standardized international procedures American Society for Testing and Materials (ASTM) SINO-ITALIAN CAMPUS

SINO-ITALIAN CAMPUS Deformation: the change of geometry and size of material response to the external load and stress. tension compression bending shear torsion Type of loads:
Strength Strength:the ability of resistant to deformation and fracture response to external loads It can be classified tensile strength,compressive strength,bending strength,shear strength and torsion strength according to different loads. The tensile-resistant strength can be given by tension test
