this paper proposed analytical solutions for the buckling analysis of rectangular single-layered graphene sheets under in-plane loading on all edges simply is supported. the characteristic equations of the graphene sheets are derived and the analysis formula is based on the nonlocal mindlin plate. this theory is considering both the small length scale effects and transverse shear deformation ef...

There are a huge number of bolted joints used in engineering applications. However, unreasonable design and use may lead to degradation failure the connected structure. Herein, finite element analysis method is investigate influence various factors on mechanical properties joints. To simulate actual assembly loading process, different steps were considered, given as: tightening step, initial lo...

BACKGROUND Following anterior cruciate ligament injury and subsequent reconstruction transverse plane tibiofemoral rotation becomes underconstrained and overconstrained, respectively. Conflicting reports exist on how rotations influence loading at the knee. This investigation aimed to determine the mechanical effects of internal and external tibial rotation offsets on knee kinematics and ligame...
