A Steady State Axisymmetric Penetration Problem for Rigid/perfectly Plastic Materials
The axisymmetric deformations of an eroding long cylindrical rod made of a rigid/perfectly plastic material penetrating at a uniform rate into a thick rigid/perfectly plastic target are studied by the finite element method. It is assumed that the deformations appear steady to an observer situated at the stagnation point and moving with it, and that the contact between the target and the penetra...
متن کاملAn Axisymmetric Torsion Problem of an Elastic Layer on a Rigid Circular Base
A solution is presented to a doubly mixed boundary value problem of the torsion of an elastic layer, partially resting on a rigid circular base by a circular rigid punch attached to its surface. This problem is reduced to a system of dual integral equations using the Boussinesq stress functions and the Hankel integral transforms. With the help of the Gegenbauer expansion formula of the Bessel f...
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 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...
