Abstract: Plates and shells constitute a large family of widely used structural elements. Under the action of thermal load, if the thermal expansion is restricted, membrane forces and bending moments will occur within the plate and shell structures and lead to large deformation which seriously affected normal...
Abstract: Dynamic responses of incompressible saturated poroelastic rods were investigated. Based on the theory of porous media, the 1D axial vibration equation for a fluid saturated elastic porous rod was established, in which the saturated porous material was modeled as a 2-phase system composed of an incom...
Abstract: The flow channel insert (FCI) is an indispensable component in the ITER. It serves as the thermal and electric insulator in the blanket module. The mechanical behaviors of the FCI were investigated under the coupling effects of magneto-thermo-fluid-mechanical fields. Numerical investigations based o...
Abstract: According to the geometrical nonlinear theory for shallow shells, the displacementtype geometrical nonlinear governing equations for shallow spherical shells under uniform pressure in uniform temperature field were derived. With the shooting method, the numerical results of axisymmetric bending and...
Abstract: A periodical model for rotor-stator rings was constructed with the meshing software, and the 3D force coupling and force-heat coupling behaviors of the rotor-stator system were computed by means of ANSYS Workbench 15.0. The influences of the force coupling and force-heat coupling on the ring end fac...
Abstract: To overcome the defects in the existing interval solving of the structural fuzzy reliability analysis method, a new method was proposed. Universal grey numbers were used to describe the basic uncertain parameters related to the probability distributions of the variables, and then these numbers were ...
Abstract: Evaluation of surrounding rock stability is a complicated system problem involving various uncertain factors. To overcome the drawbacks of conventional evaluation methods based on single-type information, a new combination evaluation method based on set pair analysis was proposed. This method made f...
Abstract: The stiffness matrix of the discrete vibrating beam model is a real symmetric 5-diagonal matrix, so the inverse problem of the vibrating beam is substantially an inverse eigenvalue problem of the real symmetric 5-diagonal matrix. The existence and uniqueness conditions for the solution to the invers...
Abstract: A class of generalized nonlinear strong-damp disturbed evolution differential equations were studied, which widely appeared in the fields of mathematics, mechanics and physics etc.. Firstly, a travelling wave transformation was introduced to convert the related problem of partial differential equati...
Abstract: Some new properties of semi-preinvexity in the sense of cones were studied. Firstly, Example 4 in the paper of PENG Zai-yun, etc.(PENG Zai-yun, LI Ke-ke, TANG Ping, HUANG Ying-quan. Characterizations and criterions of D-semiprequasi-invex mappings[J].Journal of Chongqing Normal University(Natural Sc...
Abstract: The concepts of α-admissible mappings and compatible mappings for a pair of mappings F:X4→X and g:X→X in partially ordered metric spaces were constructed. Based on this, with the iterative method, existence and uniqueness of the quadruple coincidence points for the α-admissible and compatible mappin...
