Rigid perfectly plastic two-dimensional polycrystals
We consider rigid–perfectly–plastic polycrystals in the two–dimensional anti– plane shear context. The yield sets of the grains are identified with rectangles in the plane centered at the origin whose sides have length 2 and 2M . The limit M → ∞ corresponds to the grains being rigid in one direction and ductile in the orthogonal direction. We show that for large values of M , there exist polycr...
متن کاملSteady State Penetration of Rigid Perfectly Plastic Targets
The problem of steady penetration by a semi-infinite, rigid penetrator into an infinite, rigid/perfectly plastic target has been studied. The rod is assumed to be cylindrical, with a hemispherical nose, and the target is assumed to obey the Von-Mises yield criterion with the associated flow rule. Contact between target and penetrator has been assumed to be smooth and frictionless. Results compu...
متن کاملSteady-state Penetration of Transversely Isotropic Rigid/perfectly Plastic Targets
Ahstraet-Axisymmetric deformations of a transversely isotropic, rigid/perfectly plastic target being penetrated by a long rigid cylindrical rod with an ellipsoidal nose have been analyzed. The deformations of the target appear steady to an observer situated at the penetrator nose tip. The contact between the target and the penetrator is assumed to be smooth. Computed results show that the defor...
متن کاملSteady State Penetration of Compressible Rigid Perfectly Plastic Targets
Steady state axisymmetric deformations of a homogeneous, isotropic, compressible and rigid perfectly plastic target being penetrated by a rigid cylindrical penetrator with a hemispherical nose are studied by the finite element method. The steady state is reached with respect to an observer situated on the penetrator nose and moving with it. Tillotson’s equation, restricted to mechanical deforma...
متن کاملSteady State Deformations of a Rigid Perfectly Plastic Rod Striking a Rigid Cavity
The axisymmetric steady state deformations of an infinite cylindrical rod made of a rigid/perfectly plastic material and striking a known cavity in a rigid target are analyzed by the finite element method. The contact between the deforming rod and the target surface is assumed to be smooth. It is found that the axial force experienced by the rod depends strongly upon the square of its speed. Re...
