Abstract: A compliant hinge for deployable membrane-like structures and other applications is provided. The compliant hinge generally includes a flexible intermediate portion having one or more enclosed contours connected by inner longitudinal segments along a longitudinal axis of symmetry. The enclosed contours are resiliently deformable in response to an in-plane load, including tension and shear forces. The compliant hinge allows for rotation, bending, and extension, and can interconnect rigid panels in tensioned precision structures and other applications.

Abstract: A standard tensile test device is improved to accurately measure the mechanical properties of stranded cables, ropes, and other composite structures wherein a witness is attached to the top and bottom mounting blocks holding the cable under test. The witness is comprised of two parts: a top and a bottom rod of similar diameter with the bottom rod having a smaller diameter stem on its upper end and the top rod having a hollow opening in its lower end into which the stem fits forming a witness joint. A small gap is present between the top rod and the larger diameter portion of the bottom rod. A standard extensometer is attached to the top and bottom rods of the witness spanning this small witness gap. When a force is applied to separate the mounting blocks, the gap in the witness expands the same length that the entire test specimen is stretched.

Abstract: An improved test fixture to evaluate thin composite laminates commonly used in deployable space structures. The fixture is designed to impart a pure moment into the coupon, a necessary improvement to prior test methods where results are obtained by fitting material properties in a nonlinear structural analysis of the test. Fixture mechanics allow for direct calculation of the coupon flexural modulus and allowable flexural strain based on two key measurements, fixture displacement and applied load.
