1. Plastic behavior in uniaxial deformation
1.1 Uniaxial deformation
For the sake of simplicity, and because it is commonly used, we restrict ourselves to uniaxial deformation in tension or compression at constant temperature. Assuming the specimen is carried by the Oz axis, the relevant parameters are relative elongation ε zz , and tensile stress σ zz , noted simply as ε and σ, for simplicity of exposition. The various types of test performed are :
1. deformation test with imposed strain rate
