A portable triaxial cell for beamline imaging of rocks under triaxial state of stress [PDF]
Measurement Science and Technology, 2021 Abstract With recent developments in direct imaging techniques using x-ray and neutron imaging, there is an increasing need for efficient test setups to study the mechanical and/or transport behavior of porous rocks. Bespoke designs from commercial suppliers are expensive and often difficult to modify.

Tensile deformation behavior of TRIP-aided bainitic ferrite steel in the post-necking strain region
Science and Technology of Advanced Materials: Methods, 2021 Transformation induced plasticity (TRIP) steels present a remarkable balance of strength and ductility. However, their post-necking hardening behavior, which is required for press-forming and automobile crash simulation, is unreliable because of their ...

On the damage behaviour in dual-phase DP800 steel deformed in single and combined strain paths
Materials & Design, 2023 Ductile damage in dual-phase steels deteriorates the mechanical properties, resulting in a lowered crashworthiness and a shorter life-time under cyclic loading. However, most works focus on the observation of damage under simple strain paths, even though
