Berechnung von Eigenspannungen in metallgespritzten rotationssymmetrischen Körpern

Computation of Residual Stresses in Metal-Sprayed Solid Bodies Presenting Rotation Symmetry Residual stresses are internal tensions in a workpiece without acting forces and moments on the solid body. The knowledge of the residual stresses can be very interesting because the superposition with tensions from forces and moments can produce a unfavorable state of stresses. Based on the reflektions for the computation of residual stresses in homogen materials the general equations for inhomogen materials and the equations for the special case of a solid body consisting of two layers are differentiated. A simple evaluation is shown. In a special case the solid body is taken as inhomogen, while the layers are homogen and isotropic. The equations are employed for metal-sprayed bodies and for all other laminated systems of two layers presenting rotation symmetry. There are press fits, shrink fits, clad steel a.s.o. Different hypothesis for computation the circumferential tension show two different solutions with two different results.
