PPT-Chapter 2 Strain Deformation

Whenever a force is applied to a body it will undergo deformation change the bodys shape and size The deformation can be highly visible but is often unnoticeable Generally the deformation of a body will not be uniform throughout its volume . IV-1-1 JOINTS Dry fractures with no displacement. In sedimentary rocks these joints are usually perpendicular or parallel to the bedding plane.

Ensuring that crucial materials are fit for purpose presents a challenge to developers, operators and manufacturers across many industries globally. You need assurance that your equipment and infrastructure will perform to the end of its design life with minimal maintenance, failure mitigation and with mechanical strength prioritized and planned for.  . where δ is the deformation and L is the original length, thus ε is dimensionless. . Stress-Strain Diagram . Suppose that a metal specimen be placed in tension-compression testing machine. As the axial load is gradually increased in increments, the total elongation over the gage length is measured at each increment of the load and this is continued until failure of the specimen takes place. Knowing the original cross-sectional area and length of the specimen, the normal stress σ and the strain ε can be obtained. The graph of these quantities with the stress σ along the y-axis and the strain ε along the x-axis is called the stress-strain diagram. The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium carbon structural steel. . Nam-Ho Kim. Introduction. Linear systems.
