Ensuring the strength, reliability and safety of structures requires studying issues ine-lastic deformation zones occurrence development which result from equilibrium accumula-tion damages. Material postcritical characterized by a decrease in stress level during growing deformations is one damages accumulation effects. Application theory basic provisions to carry out refined strength analysis with additional reserves identification expedient.

Consideration analytical solutions where softening are taken into account expedient illustrate main theoretical positions defor-mation mechanics. The solution hollow cylindrical solid torsion problem material stage system considered obtained. Two-link three-link approximations complete diagram considered. Dia-grams shear stresses distribution over cross-section shown; various de-formation scenarios existence noted. Loading diagrams built; torque maximum value dependence on parameters rod geometry defined. structure revealed. Conditions for implementation determined, influence Therefore, ration-ality necessity taking structural design concluded.

Safety analysis has been done for the torsion of a functionally graded thick-walled circular cylinder under internal and external pressure subjected to thermal loading. In order to determine stresses the concept of Seth’s transition theory based on generalized principal strain measure has been used. This theory simplifies the set of mechanical equations by mentioning the order of the measure of...

In this paper, we consider bifurcation from a circular cylindrical deformed configuration of a thick-walled circular cylindrical tube of incompressible isotropic elastic material subject to combined axial loading and external pressure. In particular, we examine both axisymmetric and asymmetric modes of bifurcation. The analysis is based on the three-dimensional incremental equilibrium equations...
متن کاملEffective coarse-grained simulations of super-thick multi-walled carbon nanotubes under torsion
Under torsion and beyond the buckling point, multi-walled carbon nanotubes MWCNTs develop a periodic wave-like rippling morphology. Here, we show that torsional rippling deformations can be accurately described by a simple sinusoidal shape function. Combining this observation with the geometry optimization, we develop an effective coarse-grained model that reproduces the complex nonlinear mecha...
