... Abstract The mechanical properties of a material describe the relations between the stresses acting on the material and its resulting deformations. Stresses capable of producing permanent deformations, which remain after the stresses are removed, are considered in this chapter. The effects...

... Abstract Ductile fracture results from the application of an excessive stress to a metal that has the ability to deform permanently, or plastically, prior to fracture. Careful examination and knowledge of the metal, its thermal history, and its hardness are important in determining the correct...

...: the slat will buckle quickly if the concave surface is on top. Because these parts are made from relatively high-strength steel, even though it is extremely thin, the distortion is only elastic, or temporary. There is no plastic, or permanent, deformation.

.... That is, the shear strength is the “weak link” in the system and is the controlling factor. Therefore, under a tensile force, the internal crystal structure of the metal deforms, or slips, permanently on the millions of microshear planes in the metal, resulting in lateral deformation— commonly called “necking”—prior...
