This work addresses the determination of cohesive laws in Mode I and tangential–longitudinal (TL) crack propagation system Fagus Sylvatica L. species is one ever-growing most widely used hardwood Europe for engineered timber products. Double Cantilever Beam (DCB) tests are performed. The strain energy release rate (GI) derived from R-curves by applying Compliance-Based Method (CBBM), which has ...

This paper presents a part of development non-standard method for testing cylindrical test specimens measurement fracture properties pipeline materials. structures working under pressure is based on determining mechanics parameters SENT (Single Edge Notched Tension) and new PRNT (Pipe Ring specimens. In this work, both types required were manufactured from polyamide PA12 by using SLS (selective...
