Cruciform specimen design for large plastic strain during biaxial tensile testing
Journal of Physics: Conference Series, 2018 The cruciform biaxial tensile test can be used to map the hardening evolution of the yield surface over a wide range of loading paths, which is useful for calibrating and validating the advanced material models. However, when cruciform specimens following ISO Standard 16842 are used, equivalent plastic strain in the gauge region is limited to only ~0 ...

Fire and Materials, EarlyView.ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
