Ys. Lee et al., OPTIMAL-DESIGN OF HYBRID LAMINATED COMPOSITE PLATES WITH DYNAMIC AND STATIC CONSTRAINTS, Computers & structures, 50(6), 1994, pp. 797-803
Optimization procedures are presented that consider the static and dyn
amic characteristic constraints for laminated composite plates and hyb
rid laminated composite plates subject to a concentrated load on the c
enter of the plate. The design variables adopted are ply angle or ply
thickness. Considered constraints are deflection, natural frequency an
d specific damping capacity. Using a recursive linear programming meth
od, nonlinear optimization problems are solyed, and by introducing the
design scaling factor, the number of iterations is reduced significan
tly. Relating interactive optimization procedures with the finite elem
ent method analysis, various hybrid composite plates with arbitrary bo
undary conditions can be designed optimally. In the optimization proce
dure, verification of analysis and design of the laminated composite p
lates are compared with a previous paper. Various design results are p
resented on laminated composite plates and hybrid laminated composite
plates.
