ファイバーで補強された平板の弾性特性について

抄録

The stresses in a fiber-reinforced plate produced by mechanical interaction between the fiber and the matrix are studied theoretically and experimentally. The plate bent transversely is represented by a fiber-reinforced beam, and the bending stresses caused by external bending moment or differential shrinkage are analyzed. The plate stressed two-dimensionally is represented by an infinite plate in a condition of the plane-stress in which a pair of fibers is embedded, and we analyze the stresses resulted from differential shrinkage or external compressive load regarding the fibers as a non-homogeneous elliptic inclusion.
All the analytical results are compared with photoelastic observations on rectangular epoxy plates reinforced by steel wires. The differential shrinkage is produced by curing the resin in high temperature. The requirements for modelprototype similarity are discussed.
