Abstract
The behavior of ship plating normally depends on a variety of influential factors,
namely geometric/material properties, loading characteristics, initial imperfections,
boundary conditions and deterioration arising from corrosion and fatigue cracking.
The analysis is presented for a uniaxially in-plane loaded, clamped, composite
laminated quadratic plate. The imperfection is considered as the initial deformation
due to the manufacturing operations: cosinusoidal shape in both of the longitudinal
and transverse direction. Usually, the initial deformation mode appears in the form
such as the fundamental mode of the buckling or vibration (figure 1) Variation of the
maximum transverse displacement regarding the inplane load (displacement
controlled after nonlinear buckling analysis) for three cases are presented.
