| 内容記述 | The notched strength of filament-wound composite specimens was determined for coupons with various sized semielliptic surface notches. When the part-through notches did not cut the first 0-deg layer the strength was independent of the size of the notch and was equal to the unnotched tensile strength. When the cut penetrated 0-deg layers, the specimens failed in a two-part failure mode. The first part of the failure was modeled using fracture mechanics and a straight line tangent to the fracture mechanics solution, and the second part of the failure was modeled using a failure criterion that accounted for the moduli of 0-deg and helical layers. |
