Abstract
Whole ship shock analysis (WSSA) is becoming a mandatory requirement in the
design of naval platform. One of the key technical challenges in WSSA is the
reduction of a complex ship design to a reasonable FE model size. An approach
known as \“smearing” is commonly used to idealise the ship to a manageable
number of DOFs, by using equivalent stiffness. This paper presents a novel
technique to study the localized stress and deformation of a ship section using
global parameters obtained from the WSSA. A 3D explicit finite element code is
used to compute the critically stressed areas in the whole ship and predict the
localized stresses in the ship section. This paper expounds the methodology of
stress recovery through the conversion of the displacement time history from the
whole ship to obtain the stress distributi
