Abstract
Elastic small deflection response of fiber-reinforced
laminated sector Mindlin plates are studied using Dynamic
Relaxation (DR) iterative methods. Finite-difference
discretization technique is incorporated so that the DR partial
differential velocity equations can be solved by preparing a
suitable computer code. The plate can be arranged in any
number of layers and with various fiber orientations but the
lay-ups must be symmetric with respect to the plate middle-plane.
The loading on the plate is a uniform pressure, the
boundary restraints can be either simply-supported or
clamped or a combination of both. Linearized results for
lateral displacement, radial, circumferential and twisting
stress couples and transverse shear stress resultants are
presented. Similar results are generated using the NISA
Finite Element package for comparison purposes. In most
cases the correction of the results is satisfactory .
