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 .

Elastic Materials. Strain (deformation) when stress is applied. 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.  . From fig 4 , the decline in the stress necessary to continue deformation past the maximum, point M, seems to indicate that the metal is becoming weaker. However, the cross-sectional area is decreasing rapidly within the neck region, where deformation is occurring. The stress, as computed from . Asady. Al-. Mustansiryah. University .

Stress: . when some external system of load acts on a body, the internal forces (equal & opposite) are set up at various section of the body, which resist the external force. This force per unit area at any section is known as stress..
