عن مذكّرة Convergence and Accuracy of Dynamic Relaxation Technique in Determination of Central Deflection of Composite Rectangular Laminates:
The convergence and accuracy of the Dynamic
Relaxation (DR) solutions for elastic large deflection
response of isotropic, orthotropic, and laminated plates
are established by comparison with various exact and
approximate solutions. The present Dynamic
Relaxation method (DR) coupled with finite differences
method shows a fairly good agreement with other
analytical and numerical methods used in the verification
scheme.
It was found that: The convergence and accuracy of the
DR solution is dependent on several factors including
boundary conditions, mesh size and type, fictitious
densities, damping coefficients, time increment and
applied load. Also, the DR large deflection program
using uniform finite differences meshes can be
employed in the analysis of different thicknesses for
isotropic, orthotropic or laminated plates under uniform
loads. All the comparison results for simply supported
(SS4) edge conditions showed that deflection is almost
dependent on the direction of the applied load or the
arrangement of the layers.
