The high strain-rate and temperature properties of ultra-high molecular weight polyethylene (UHMWPE) composites are limitedly available in the public domain, primarily due to challenges in gripping the extremely strong material during testing. In thi

Comments on W.S. Lei’s discussion of 'An engineering methodology for constraint corrections of elastic–plastic fracture toughness – Part II: Effects of specimen geometry and plastic strain on cleavage fracture predictions' by C. Ruggieri, R.G. Savioli and R.H. Dodds

In recent communication to this journal, Lei (2015) raised several questions on previous work by Ruggieri et al. (2015) which extended a modified Weibull stress ( σ w ) model incorporating the influence of plastic strain on cleavage fracture to corr
