There are described analysis of stress state in the bend and influence of spherical stress tensor increasing on bending process.
Key words: rubber pad bending, non-rigid die, spherical stress tensor, spring-back angle
during bending in bend increases spherical stress tensor component and also increases formability of bent material.
