An exact solution on the stress distribution of fillet welds is obtained in this paper. This solution can be used not only for estimating the accuracy of the present design method of fillet welds but also for establishing a new design method.
Based on the Ref. , the displacement and stress distributions in a spherically isotropic cone subjected to concentrated loads at apex are studied. The displacement and stresses are given explicily for the cone in compression torsion and bending cases, respectively, based on the situation of...
In this paper, a general matrix decomposition scheme as well as an element-by-element relanation algorithm combined with step-by-step integration method is presented for transient dynamic problems, thus the finite element method can be from forming global stiffness matrix global mass matrix as...
The stability of inviscid incompressible swirling flow with slowly divergence is investigated. A multiple scale expansion is used to develop a linear stability study of slowly divergent swirling flow with non-axisymmetric disturbances. The differential equations of zero-order and first-order...
This paper presents the integration methods for Vacco dynamics equations of nonlinear nonholonomic system. First, Vacco dynamics equations are written in the canonical form and the field form. Second, the gradient methods, the single-component methods and the field method are used to integrate...
In this paper, the author uses the theory of fluid mechanics, dynamics of fluids in porous media, gas seepage flow in coal seams and combines the tests in the laboratory with the actual coal infusion to have an investigating and study from the theory to the mechanism of coal infusion to wet coal...
In this paper, we discuss the existence and stability of solution for two semihomogeneous boundary value problems. The relative theorems in [1, 2] are extended, Meanwhile, we obtain some new results.
In this paper, we study the recursive equations under the recursive boundary conditions forW
(n=0, 1, 2....N: m=1, 2....M), which derived by the “two-variable method” in the preceding paper. We then solve these problems by using the method of regular...
In this paper, the mechanical properties of holonomic systems and non-holonomic systems are studied. This is an important and urgent problem.
The results in Ref.  are not suitable for the cases of β≥2. For this reason, by using the methods in Ref  and Ref , we derive the general expressions of anisotropic plastic fields at a rapidly propagating plane-stress crack-tip for both the cases of β=2 and β>2.
