The shear mechanical behavior of joint surfaces is crucial for the safety and stability of rock engineering. Under constant normal load (CNL) conditions, the boundary element method is employed to ...

(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 ...

In the seismic resistant design of moment-resisting frames, the beam-column joint is regarded as a crucial point for consideration. Post–earthquake research indicates that, under high shear stress, ...
