Abstract: Abstract Based on the constant-amplitude fatigue experiment, a new residual stiffness model combining with power spectral density is proposed to adapt random stress states. The random loading process can be divided into multi-level variable amplitude… read more here.

Abstract: This article presents an online statistical life prediction method based on both historical and local residual-stiffness information to reduce the effect of dispersive mechanical properties of fiber-reinforced plastic structures. Normalized residual-stiffness curves obtained from the… read more here.
