(Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper ...

This study investigated the concrete-to-concrete friction behavior under dynamic cyclic loading at different loading rates, vertical loads, and surface roughness. The present work answers essential ...

To ensure the coupler’s adequate retraction in rail vehicle collisions, this study systematically investigates the shear fracture behavior of bolts, focusing on the effects of geometric parameters and ...
