The Influence of General Surface Loading on Penetration of a Circular Punch into an Elastic Stratum [article]

B. Rogowski, D. Zaręba
1998
The first of the authors (B. R.) derived an expression for the pressure distribution inside a circular region with vanishing shear tractions and norma! displacements, due to the application of the forces distributed along the circumference on an elastic transversely isotropic half-space. This result is used to derive the relationships between the forces, moments and indentations for a punch acting on an elastic half-space. The results are given in terms of elementary functions. The influence of

The stress intensity factor of Mode I related to non-symmetric stress distribution in the vicinity of an external crack under generał surface loading, symmetric with respect to the crack piane, is also presented in terms of elementary functions.
