Document Summary

The material discussed in this section is to set the context for the course. Students are encouraged to reference such books and to review their mece 260 notes. 2. 1 restrictions and assumptions for this course 2-4. 2. 3 other important material characteristics of materials 2-21. 2. 3. 4 poisson"s ratio: ratio of lateral to axial strain 2-28. The following section details the important material restrictions of this course. We shall assume that all materials used in this course are. This means that properties are the same through out the component we are analysing. Figure 2-1: general body with homogenous and isotropic elastic constants. For isotropic materials there is a relationship between the three elastic constants: (2. 1) (2. 2) Let us define the following quantities for the figures to follow: : normal engineering stress defined as instantaneous applied load divided by original cross sectional area. : normal engineering strain defined as the change in length divided by the original length.
