Beam188是三维线性（2节点）或者二次梁单元。每个节点有六个或者七个自由度，自由度的个数取决于KEYOPT(1)的值。当KEYOPT(1)＝0（缺省）时，每个节点有六个自由度；节点坐标系的x、y、z方向的平动和绕x、y、z轴的转动。当KEYOPT(1)=1时，每个节点有七个自由度，这时引入了第七个自由度（横截面的翘曲）...
A novel approach is presented for the analysis of spatial beam elements with end releases, in which, for each joint in the structure, an additional (slave) set of kinematic variables is introduced, which is directly related to the existing (master) set of variables at that node. This relatio...
Two-noded curved beam elements, CMLC and IMLC, are developed on the basis of Timoshenko's beam theory and curvilinear co-ordinates. These elements are developed by the separation of the radial displacement into the bending and the shear deflection and the projection of the shear deflection into...
The space of curves which are extremal for the total curvature energy is well understood in isotropic homogeneous 3-spaces, said otherwise, spaces of constant curvature. In this paper we obtain that space of extremals in homogeneous 3-spaces whose isometry group has dimension four, that is, rota...
A shear flexible (i.e. Timoshenko) quadratic isoparametric beam element with two degrees of freedom per node is critically examined from the point of view ... G Prathap,CR Babu - 《International Journal for Numerical Methods in Engineering》 被引量: 46发表: 2010年 ...
Both the classical and Timoshenko beam theories are used to analyze the DCB specimens. A novel two-node rod element is developed to model the stitches along the crack plane and the micromechanical stitching models available in the literature are adopted to simulate the mechanical behavior of the ...

beam elementsteel-concrete composite structuresSteel-concrete members are an example of layered systems with interlayer slip. To analyze such systems theoretically, layered beam elements, derived from the standard two-noded ones, may be employed. Special LB-ele...
Originality/value – The present investigation introduces new shape functions, namely 3-node Basic Displacement Functions (BDFs) extended from 2-node functions, and then compares its performance with previous element.doi:10.1177/1077546310396430Attarnejad, R....
