Dislocation creep is a deformation mechanism transporting shear through the crystal lattice by the motion of line defects, called dislocations. This mechanism involves the elementary processes of ...

Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...

Plastic fantastic? Quasicrystal deformations and bending observed. When shrunk to the nanoscale, quasicrystals become plastic. That is the finding of an international team of researchers, which says ...

Shoulder instability occurs when your shoulder joint (ball and socket) has lost is normal alignment (ball resting symmetrically in the socket), which causes your arm to lose its support. The most ...

Despite being composed of solid rocks, the Earth's mantle, which extends to a depth of ~2890 km below the crust, undergoes convective flow by removing heat from the Earth's interior. This process ...
