Abstract In this presentation, large deflection analysis for thin-plate bending problem using Hermite Reproducing Kernel (HRK) approximation is presented. HRK approximation for thin-plate bending problem is one of meshfree/particle approaches and is proposed by Wang [1]. The deflection and rotations are represented by the Hermite-type approximation. In the formulation, the rotations are represented by the differentiation of deflection and the approximation is satisfied Kirchhoff Mode Reproducing Condition (KMRC). Sub-domain stabilized nodal conforming integration is adopted to enforce integration constraint in the numerical integration. Total Lagrangian method is adopted to solve thin-plate bending problem with geometrical non-linearity. Green-Lagrange strain and second Piola… More >

Abstract Due to the complexity of thermal elastic problems, analytic solutions have been obtained only for some axisymmetrical problems and simply problems. Yu De-hao discussed bending problems of plates with the natural boundary element method. Using the above method, Li Shun-cai discussed the bending problems of solid circular plates] and bending deflections for annular infinite plates under the boundary loads.

On the basis of the same method, expanding the boundary slope into Fourier series, and using several convolution formulae, the boundary integral formula and natural boundary integral equation for the boundary value problems of thermal bending of Circular Plates are… More >

Abstract Welded tubular structures are widely used in many constructions, such as offshore platforms, which are all consisted of welded tubular members. There is high stress concentration at the intersection between the chord and the brace. As high sress concentration exists along the weld toe, failure usually occurs in this region. To increase the bearing capacity of a tubular joint, it is necessary to take measures to reinforce the region around the weld toe. Therefore, the static strength of rectangular hollow section (RHS) T-joints with local chord reinforcement under in-plane bending load is investigated by using finite element method. To study… More >

Abstract The elbow pipe is the crucial component of the piping system in many engineering fields such as metallurgical industry, material industry, petrochemical industry and chemical industry. Under high temperature and pressure (bulky flux, high velocity of flow) conditions, the non-uniformity of pressure loads has intensified the stress concentration in elbow pipe position. Meanwhile, it occurs obviously in destruction and expiration due to the disfigurement of manufactural technics and partial intensity insufficient. Therefore, the analysis of flow characteristics for elbow and the calculation formula of pressure in elbow are of important theoretical significance and applied value.

Abstract Abstract Al alloys have been widely used as engineering materials in many machines and structures because of their excellent properties such as high specific strength, high resistance to corrosion and easy to recycle. Especially, high strength Al alloys are effective to reduce environment load through achieving low fuel consumption in automobile engines. On the other hand, high strength Al alloys have no definite fatigue limit and their fatigue strengths are very low in comparison with their high static strengths. It is important to know the fatigue strength of high strength Al alloys in the long life region beyond 10⁷ cycles… More >

Abstract This paper focuses on the interface energy release rate of elastic multilayered beam subjected to four-point bending. Linear elastic fracture mechanics (LEFM) and extended finite element method (XFEM) are adopted to investigate the interface fracture of composite beams. Numerical results obtained from simulations not only verify the accuracy of closed-form solutions for the steady-state interface energy release rate, but also provide the evolution history of interface energy release rate under different crack length. In addition, non-dimensional parametric analyses for interface fracture energy release rate are carried out for the discussion of effects of crack length ratio, elastic modulus ratio, and… More >

Abstract In this article, the bending equations of thick annular sector plates are derived based on the third-order shear deformation theory (TSDT). Using a function, called boundary layer function, the coupled system of equations is converted into two decoupled equations and solved analytically. It is shown that the value of the boundary layer function for TSDT is higher than that of the Mindlin theory. Thus, variations of stress components in the edge zone of the plate are more significant. It is seen that there exist no boundary layer, a weak boundary layer, and a strong boundary layer effect for simply supported,… More >

Abstract In this work, a new equation to predict the springback in the bending and rolling processes of metallic sheet is presented. This equation has been experimentally applied in the design of a wood truncated cone to form an aluminum sheet truncated cone. Kalpakjian's equation was also applied but Damian's equation has given the best performance. More >

Abstract An initial-boundary value problem for bending of a piecewise homogeneous thermoelastic plate with transverse shear deformation [1] is considered. The unique solvability in distributional spaces is proved by means of a combination of the Laplace transformation and variational methods. This is the first, and essential, step in the construction of boundary element methods for numerical approximations of the solution. The model without thermal effects has been studied in [2]--[6].

Abstract A high-order wavelet method is developed for general nonlinear boundary value problems with complex boundaries in mechanics. This method is established based on wavelet approximation of multiple integrals of interval bounded functions combined with an accurate and adjustable boundary extension technique. The convergence order of this approximation has been proven to be N as long as a typical family of wavelets named Coiflets with N-1 vanishing moment are adopted, which can be any positive even integers. Error analysis has proven that the proposed method is in accuracy of order N, and condition numbers of relevant matrices are almost independent of… More >
