✦ Synopsis

The influence of locally varying specimen thickness on the shape of the shadow spot and, hence, on the stress intensity factor is of first order but for all practical cases comparable with the experimental data scatter.

## Abstract This paper investigates numerically and experimentally the influence of initial geometric imperfections on the critical loads of initially stretched thick hyperelastic cylindrical shells under increasing uniform internal pressure. Imperfections in shells can have a global or local chara

The problem about identification of resistance forces acting on a drill column moving in an inclined borehole is stated. It is supposed that the well trajectories can have geometrical imperfections in the shape of cylindrical spiral or plane cosinusoidal curves. The system of ordinary differential e
