Abstract Dislocation mobility, which dictates the response of dislocations to an applied stress, is a fundamental property of crystalline materials that governs the evolution of plastic deformation. Traditional approaches for deriving mobility laws r

Non-Schmid effects in a representative refractory multi-principal element alloy (MPEA), MoNbTi, are investigated using molecular statics (MS) and phase field dislocation dynamics (PFDD). In addition to imposing a statistical distribution for the ener

There is an increased incidence of submandibular gland duct developing sialoliths. Among them the sialoliths attaining a size of more than 1.5 cms are rare. Here we present a case with an abnormally sized sialolith in Wharton’s duct and a review of
