Effect of mode of pressing on the stressed-strained state of bushing-type parts
- 11 Downloads
The solution of the boundary-value problem of the cold-pressing process does not depend on the type of loading surface. It is determined by the axial and lateral pressures as functions of porosity.
The tangential stress and additional porosity due to external friction are given by the solution of a Dirichlet problem for a system of equations of the elliptic type.
To each mode of pressing there corresponds a specific character of bending of layers parallel to the basis plane before pressing.
