Optimization of Wood Fiber Orientation Angle in Outer Layers of Variable Stiffness Plywood Plate
The new optimization method for fiber orientation
angle optimization of symmetrical multilayer plates like plywood is
proposed. Optimization method consists of seeking for minimal
compliance by choosing appropriate fiber orientation angle in outer
layers of flexural plate. The discrete values of fiber orientation angles
are used in method. Optimization results of simply supported plate
and multispan plate with uniformly distributed load are provided.
Results show that stiffness could be increased up to 20% by changing
wood fiber orientation angle in one or two outer layers.
