The state of stress at a given point in a material is represented as a 3×3 symmetric matrix of values called a tensor. The state of strain at a material point is also a 3×3 symmetric tensor. Stress ...

In material science, understanding the difference between true stress and true strain compared to engineering stress and ...

This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object ...

Prior to this stress-strain condition the plastic deformation occurs throughout the sample and the material deforms under constant volume conditions. At the UTS deformation becomes localized in the ...

For the material illustrated, the volume fraction of the ductile matrix is large enough that it can take the increased load without failing. The composite continues to deform along the matrix ...
