Elastic criterion for dislocation nucleation
The notion of theoretical strength, the critical stress at which a perfect crystal under uniform loading becomes structurally unstable, is extended to non-uniform loading. A position-dependent defect nucleation criterion has been derived and applied in molecular dynamics (MD) and finite-element simulations of dislocation emission in single-crystal nanoindentation. The resulting measure has the ...
متن کاملHangman’s Fracture with Concomitant Atlantoaxial Dislocation: a Case Report
Background: Concomitant Hangman’s fracture and atlantoaxial subluxation is a rare phenomenon. Herein, we reported a victim of motor vehicle crash with traumatic spondylolisthesis of the axis and atlantoaxial rotatory dislocation. Case presentation: the patient was a 32 years old female with a chief complaint of severe neck pain and normal neurologic examination except for mild torticollis. Ima...
متن کاملPosterior Hip Fracture -Dislocation Associated with Ipsilateral Intertrochantric Fracture; a Rare Case Report
Hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. We present the case of a 26 year old patient involved in motor vehicle accident. Clinical and imaging (radiography, CT) examination revealed an intertrochanteric fracture associated with ipsi...
