Features of control of nonsingularity in modeling of separating processes of pressure working
Abstract
The greatest and the least positive nonregularized stiffness matrix eigenvalues are estimated. The estimation is based on finite elements from the centre of deformation and on finite elements of one row. Suitability of the estimation for control of nonsingularity is shown.
Keywords:
stiffness matrix; nonsingularity; FEM; blanking processes.
