On static and fatigue strength determination of carbon fibre/epoxy composites Part 2: theoretical formulation
This paper outlines a practical model to evaluate fatigue residual strength for reliability-based design. A new formulation is presented for a fatigue-driven residual strength surface based on controlling fatigue strain. The parameter determination formulae of the residual strength surface are established to deal with the test data effectively and easily. Finally, the model is applied to experimental data, demonstrating the practical and effective use of the proposed model. It is shown that fatigue-driven residual strength can be obtained realistically according to the small sample test data using the new formulae.

Abstract
This paper outlines a practical model to evaluate fatigue residual strength for reliability-based design. A new formulation is presented for a fatigue-driven residual strength surface based on controlling fatigue strain. The parameter determination formulae of the residual strength surface are established to deal with the test data effectively and easily. Finally, the model is applied to experimental data, demonstrating the practical and effective use of the proposed model. It is shown that fatigue-driven residual strength can be obtained realistically according to the small sample test data using the new formulae.
