TL;DR: In this article, the frequency domain formula of equivalent Lemaitre stress taking into account the hydrostatic stress effect is first introduced, and the corresponding method for estimating fatigue life under multiaxial random loading is developed based on multi-axial S-N curve.

TL;DR: In this article, two different low velocity impact experiments were designed to study the impact damage behavior of polymer bonded explosives (PBXs) and a damage constitutive model with viscoelastic response and statistical fracture for PBXs was developed.

TL;DR: In this paper, the authors investigated stress ratio effect on fiber bridging significance in mode I fatigue delamination growth of composite materials and determined fatigue resistance curves (R-curves) of different stress ratios and compared with the quasi-static R-curve.

TL;DR: In this paper, the strength prediction of open-hole fibre-reinforced composite laminate under compression is studied. And the authors propose a method to predict the strength of composite structures under compression by modelling fiber, matrix damage and delaminations.

TL;DR: In this paper, a modified Paris relation was proposed and used to determine fatigue delamination with fiber bridging in composite laminates and a master resistance curve was obtained for different amounts of fibre bridging.
