โœฆ Synopsis

A survey of existing solutions describing the stress distribution around the crack tip of an initially curved sheet is made and a method for esttmating approximate stress intensity factors of other more complicated shell geometries is discussed.

A co-rotational finite element formulation of slender curved beam element is presented to investigate the effect of member initial curvature on the dynamic behaviour of planar flexible mechanisms. The Euler-Bernoulli hypothesis and the initial curvature are properly considered for the kinematics of
