Lecture

Simple Traction or Compression

Description

This lecture introduces the general notions and hypotheses related to simple traction or compression, including the analysis of the state of deformation, expression of forces, and internal stresses. It covers the equilibrium equations, stress state analysis, and the concept of strain energy in the elastic domain. The lecture also discusses the relevance of engineers in testing and analyzing stress states in materials, with practical examples such as hot crimping of steel-copper rings. Various concepts like principal planes, Mohr circles, and shear stresses are explored to understand the behavior of materials under tension or compression.
