Measuring Elasticity in Aluminum Bars

Measuring elasticity in aluminum bars helps civil engineers connect force, stress, and strain to the way a material changes shape. Because each civil engineering structure is unique and costly to reproduce, engineers depend on analytical models instead of full-scale testing for every design. These simplified models help chec...

Most engineering design today uses the theory of elasticity and several material constants to estimate the performance criteria of a structure.

In contrast to the production of cars, for example, where millions of identical copies are made, an extensive prototype testing is possible. Each civil engineering structure is unique, and its des...
