PLASTIC DEFORMATION AND stress - strain CURVES BACKGROUND Unit: PLASTIC DEFORMATION and stress - strain Curves Introduction In the last unit we studied the elastic response of materials to externally applied loads. All the loads applied were well below the elastic limit of the materials so no permanent DEFORMATION occurred in the sample. In this unit we will continue our study of the effects of externally applied forces and will apply loads large enough to cause permanent DEFORMATION and eventually fracture . Objectives After studying this unit and completing the lab assignment you should be able to perform the following tasks: 1. Write definitions for the following terms, including SI and English units when appropriate.
