Shear dominated deformation with curved beaks in folding–shearing
The International Journal of Advanced Manufacturing TechnologyAbstract The deep drawing process in the automotive industry generates up to 45% material waste. To address this issue, the folding–shearing process was developed as a drop-in solution, enabling the formation of parts in pure shear with minimal thickness variation.

Failure and Deformation of Sand in Torsional Shear
Soils and Foundations, 1986 ABSTRACT The deformation and strength characteristics of sand was studied by means of the torsional shear tests on hollow cylindrical samples with a height of 20 cm, an outer radius of 5 cm and an inner radius of 3 cm. It was found that in order to obtain accurate results it is essential both to very precisely measure the axial load, the torque and ...

Superconductivity in Compression-Shear Deformed Diamond
Physical Review Letters, 2020 Diamond is a prototypical ultrawide band gap semiconductor, but turns into a superconductor with a critical temperature T_{c}≈4 K near 3% boron doping [E. A. Ekimov et al., Nature (London) 428, 542 (2004)NATUAS0028-083610.1038/nature02449]. Here we unveil a surprising new route to superconductivity in undoped diamond by compression-shear deformation ...

Advanced Engineering Materials, EarlyView.This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight
