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 ...

www.mit.edu1.1 Stress, strain, and displacement ! wave equation stress strain displacement constitutive law motion w Figure 1.1: Relationship of each parame-ter. From the relationship between stress, strain, and displacement, we can derive a 3D elastic wave equation. Figure 1.1 shows relationships between each pair of parameters. In this section, I will ...
Two Dimensional Analysis – Plane Stress and Plane Strain
academic.csuohio.edudimensional constant strain and linear strain element we ignored displacements in the z direction. Here we do not. We could wave our hands over the constant strain and linear strain elements and mumble something regarding plane stress or plane strain and somewhat ignore displacements in the z direction.

www.ce.memphis.eduStep 3 -Strain-Displacement and Stress-Strain Relationships To construct the element stiffness matrix, determine the strain, which is defined in terms of the derivative of the displacement with respect to x. The displacement u, however, is now a function of s so we must apply the chain rule of differentiation to the function u as follows: du du dx
