A Failed Mechanical Part - Its Analysis
And Design
Author(s)

Abstract
The purpose of this paper was to determine the stress conditions within a
mechanical part that failed catastrophically while being tested. The method used
for the determination of the stresses was the LUSAS 12.1 finite element
calculation approach (FEA). The part in question was a hydraulic brake cylinder,
which, due to a failure in the test regulating valves, was subjected to an internal
pressure at least three times its normal operating stress, with consequent rupture
of the cylinder wall. The explosion produced a crack which originated at the
pressure inlet orifice in the cylinder wall. A design was proposed based on
LUSAS analysis.
Introduction
The crack begins at the hole made for the pressure inlet running, in both
directions, practically ta
