The FEM was initiated in structural mechanics, and the symmetry of element stiffness matrix means symplectic conservation. Based on the statement that the element strain energy is a fiinction of the two end displacements, the typical statements of analytical mechanics, i.e. both the Lagrange ...
Feminism in the Nordic countries was primarily formulated in terms of ‘state feminism’. The women’s movement cooperated with feminist gov
Thirteen high-strength concrete, simply supported composite beams with a span of 9 ft (2743 mm) were tested to failure, and their general structural bendin... B Chen,EG Nawy - 《Aci Structural Journal》 被引量: 14发表: 1994年 Numerical Analysis on Flexural Capacity of Prestressed Steel Rein...
Elements: Both continuum and structural elements are supported. The continuum elementa can be utilized for both structural and thermal analysis. Specifically: Continuum Elements 2D Tri3 Tri6 Quad4 Quad8 Quad9 Continuum Elements 3D Tet4 Tet10 Hexa8 Hexa20 Hexa27 Wedge6 Wedge15 Wedge18 Pyra5 ...
Pounding of neighbouring construction of structures due to seismic excitation increases the damage of structural components or even causes collapse of structures. Among the possible building damages, earthquake induced pounding has been commonly observed in several earthquakes. Therefore it is imperative to...
In the implicit FEM solver for nonlinear static problems, the tangential material matrices at each Gauss point are required to be accurately evaluated in t
Calculation of the problem in each element Assembly accounting for boundary conditions between the elements Solution via iterative solvers or direct solution methods FEM can be applied to various problems, from Maxwell’s equations to fluid simulation, heat transport or structural analysis. ...
Here, a method is presented to describe geometrically structural timber parts containing knots in a three-dimensional volume model. For homogeneous timber free of knots, the grain course can be assumed to run parallel to the stem axis. However, in the area of branches the fibre orientation is ...
BEM-FEM acoustic-structural coupling for spacecraft structure incorporating treatment of irregular frequencies Acoustic disturbances and the resulting structural vibration is a very significant problem in aerospace engineering. The magnitude of the acoustic loads tr... H Djojodihardjo 被引量: 10发表: 20...
