www.web.stanford.eduIncrements of the components of stress in the x-direction. Strain and Displacement The components of displacement in the x-, y-, and z- directions is often denoted by u, v, and w. The strain (engineering) is the change in length divided by the original length, which gives the strain components in the three directions:; ; and the components of ...
2.080 Structural Mechanics Lecture 2: The Concept of Strain
ocw.mit.edustrain serves to de ne a corresponding stress through the work conjugacy principle. Finally the equilibrium equation can be derived by considering compatible elds of strain and displacement increments, as explained in Lecture 3. The present author sees the engineering world through the magnitude and shape of the deforming bodies. This point of ...
