The first ply failure in composite laminates are studied by 3-D fracture mechanic approach. The fracture model is based on a crack embedded in one of the inner layers. Numeriil results for the case of "angle ply" laminates are based on a general 3-D finite difference progtam. Stress intensi~ factor

The fracture mechanics of fiber-reinforced materials differs radically from that of 'homogeneous' materials. The combination of high-strength, high-modulus, brittle fibers having significant scatter in strength levels with relatively low-strength, tow-stiffness matrices give rise to modes of interna
Ah&met-Welded and unwelded specimens of an air-melted laminar composite steel armor were tested for degradation of strength from ballistic impact. Specimens were impacted with cal. 0.30 AP and ball projectiles at various velocities and O-degree obliquity. During impact, specimens were tensile loaded
Six hundred short sections taken from 23 flatsawn 2 x 12-inch planks of construction grade Douglas-fir were tested in tension perpendicular to grain. ~ost of the specimens contained defects in the form of checks, knots, resin streaks, pitch pockets, and pith. Checks were found to be the major streng
