The discussion centers on the relationship between elastic deformation and reduction of area in ductile materials during tensile testing. It confirms that reduction of area can occur during elastic deformation, primarily explained through the concept of Poisson's ratio. For isotropic materials, this involves two parameters: Young's modulus and Poisson's ratio. In contrast, anisotropic materials may exhibit up to 21 parameters affecting their deformation characteristics.
PREREQUISITESMaterial scientists, mechanical engineers, and students studying material properties and deformation behavior in ductile materials.
phydis said:In the tensile test practical for ductile materials, up to the elastic limit, the deformation is recoverable (no line defects).
Yes. Look up "Poisson's ratio".My question is can there be a reduction of area with the elastic deformation?
What sort of answer do you want? Poisson's ratio described what happens, for isotropic materials. For anisotropic materials the concept is similar but there can be up to 21 different parameters rather than just 2 (Young's modulus and Poisson's ratio).If yes, how it happens?
