Detailed explanation-1: -Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
Detailed explanation-2: -Plastics refer to these materials with low yield strengths. A common example is plasticine or play-doh. It is a mixture of clay and mineral oil.
Detailed explanation-3: -Plastic deformation occurs when a material is stressed above its elas-tic limit, i.e. beyond the yield point, as illustrated in Figure 1. The resulting plastic deformation is permanent and cannot be recovered by simply removing the stress that caused the deformation.
Detailed explanation-4: -Plastics. Metals. Soils. Rocks. Concrete.
