Elasto-plastic Stress Analysis of a Prismatic Bar under Combined Bending and Torsion

Optimal plastic design of a bar under combined torsion, bending and shear

Optimal plastic design of a bar or beam under torsion with superposed bending and shear is obtained via the boundary perturbation method. Effects of bending and shear are expressed by a small parameter α. The results of optimization of solid bars and of hollow bars are shown.

Hot Spot Stress Determination for a Tubular T-Joint under Combined Axial and Bending Loading

Finite element analysis of a tubular T-joint subjected to various loading conditions including pure axial loading, pure in-plane bending (IPB) and different ratios of axial loading to in-plane bending loading has been carried out. This effort has been established to estimate magnitudes of the peak hot spot stresses (HSS) at the brace/chord intersection and to find the corresponding locations as...

Combined Plastic Bending and Compression or Tension

So far we have assumed that a plastic hinge forms if the bending moment in a critical cross section reaches the plastic limit value, M0. We have tacitly neglected the effect of the other internal forces on the formation of the yield hinge. This effect, however, can be appreciable, for example in multi-storey frames or frames with a large horizontal thrust where the axial forces are large. So, w...

Bending Analysis of Multi-Layered Graphene Sheets Under Combined Non-Uniform Shear and Normal Tractions

Bending analysis of multilayer graphene sheets (MLGSs) subjected to non-uniform shear and normal tractions is presented. The constitutive relations are considered to be non-classical based on nonlocal theory of elasticity. Based on the differential transformation method, numerical illustrations are carried out for circular and annular geometries. The effects of nano scale parameter, radius of c...
