Abstract

Displacement results of plane boundary collocation analysis are given for various locations on the inner boundaries of radially cracked ring segments (C-shaped specimens) subject to two complementary types of loading. Results are presented for ratios of outer to inner radius Ro/Ri in the range of 1.1 to 2.5 and ratios in the range of 1.1 to 2.5 and ratios a/W in the range 0.1 to 0.8, where a is the crack length for a specimen of wall thickness W. By combination of these results the resultant displacement coefficient Δ or the corresponding influence coefficient E'BV/P can be obtained for any practical load line location of a pinloaded specimen.

Keywords:
displacement, fractures (materials), loads (forces)
