The plane strain bending process is simulated in abaqus standard.
If friction exists more than necessary it has a negative impact on characteristics of a product.
Johan hol development manager from triboform engineering describes frictional influences that are unique to ahss forming and how the accuracy of predicting ahss automotive parts forming may be increased by using an alternative friction model.
Any type of friction will increase force hence stresses in the material.

Abstract the frictional behavior of a number of conventional tool materials used in the sheet forming industry has been studied by a recently developed tribotester based on flat die strip.
Die and blankholder surfaces for deep drawing sheet metal must be as smooth as possible they should be ground and lapped to mitigate friction.
Various lubricants are used to reduce the friction during the metal forming.
In sheet metal forming friction has a major role in knowing the properties of metals.
The results further showed that the surface topography and sample orientation in the rolling direction of the sheet are significant factors that influence the friction coefficient.
