Thinking the Flesh with Paul Ricoeurd that are describe in the book are summarized. The starting point is a basic model for the dislocation density that is used to derive expression for tensile and creep properties. It is described how the accuracy of the basic models can be verified. For the creep models it is described that they are

Thinking the Flesh with Paul Ricoeur result of a balance between work hardening and recovery processes, which allows for a continues plastic deformation without raising the stress. The starting point for the basic modeling of creep is a differential equation for the dislocation density that describes how it varies with strain or time.

Heidegger and the Question of Physicsrved for an austenitic stainless steel. The time dependence of the primary creep verifies that it is dislocation creep. An other example is for Al at very high temperatures (Harper-Dorn creep), where at sufficiently low stresses, the stress exponent approaches 1. For both materials higher stresses g

This gives the wrong temperature dependence and overestimates PH. It was for a long time thought that it was an energy barrier for climb across particles that
