Development of Stress-Strain Models for Energy-Storing Systems,
Abstract
The report is an attempt to arrive at a useful stress-strain model for batteries. The first objective is to formulate and justify the meaning of stress and strain and similar concepts related to the performance and aging of batteries. A second objective is to formulate mathematical relationships for various combinations of springs, dashpots, and their analogs. A third objective is to associate specific processes and components in a battery with one or more models growing out of results from Objectives 1 and 2. In attempting to reach the first objective it seemed necessary to consider the general meaning of stress, strain, force, displacement, strain-rate, and acceleration, for individual forms of energy. The report expands on the generalized meaning of stress and strain for six forms of energy: (1) mechanical energy, (2) surface energy, (3) volume expansion energy, (4) electrical energy, (5) thermal energy, and (6) chemical energy.
