Description

Elastic-Plastic Bending of Vertical Supports of Drilling Platforms

Result

Bending of vertical beams with the SD-effect and own weight under a constant moment or a concentrated load at the end of the beam is considered. The constant moment simulates the pressure of a uniform ice field, and the concentrated load simulates the pressure of an iceberg or ice hummock. To solve this problem, the Ilyushin model of perfect plasticity is used. The problem is solved analytically and numerically. As an example the bending of the beam with the SD-effect, own weight and hydrostatic pressure is considered. The material of the beam is a steel A40X. The classical solutions for isotropic beam and beam made of material with the SD-effect are compared with soft package COMSOL.
