Low velocity impact response and post impact compression behavior of BMI matrix composites

open access: yesCailiao gongcheng, 2022
A novel kind of lattice-distributed ESTM-fabrics was developed by using polyethersulfone(PES) and U3160.The loading amounts of PES on ESTM-fabrics are 15 g/cm2(ES-15), 25 g/cm2(ES-25), 35 g/cm2(ES-35), respectively.

A probabilistic fatigue crack growth life approach to the definition of inspection intervals for railway axles

open access: yesFracture and Structural Integrity, 2022
Different options that rely on fracture mechanics are currently used in engineering during the design and assessment of components. One of the most important aspects is the time taken for a crack to extend to its critical size.
