EU Mechanical properties - 4PUMPMEC

Goal(s)

• To know the relationship between the microstructure of a material and its mechanical properties (yield limit, plasticity)
• To understand the physical mechanisms that control the constitutive equations for the plasticity of structural materials at room temperature and a high temperature
• To feel comfortable with the tools of continuum mechanics
• To know the formalism of basic constitutive equations used to model the mechanical behavior of materials
• To understand the mechanical properties of polymers
