In this paper the stresses obtained for various (thin) shell structures by using two types of doubly curved finite elements are compared with published information. One of the elements—a ring shell element—is designed to analyze axisymmetric structures such as cylinders and hyperboloids. The ...
performance of the higher-order element as compared to commonly used lower order shell elements in predicting the variations of stress resultants and stresses, three example problems involving a simply supported skew plate, a corner supported square plate, and a clamped cylindrical shell are solved. ...

(1995) computed displacements using shell type of elements. More recently, Kennedy (2008) proposed a hybrid model in which shrinkage data measured on injection-molded specimens are used to calibrate com- puted residual stresses. Boundary conditions employed inside the mold, dur- ing filling, ...
In the finite element method, the geometry is subdivided into small patches called finite elements that make up a mesh. Within each element, there is an assumption about the variation of the field to be solved for. It is approximated by theshape functions. Most commonly, the shape functions ...
A three-dimensional model with shell elements is used, with the Ansys finite element program, to simulate a GMAW welding process in an AISI 516 carbon steel plate. The objective of this work is to approximate the volume change effect on welding residual stresses by using a modified curve of ...
Are you using FEA with bean elements for each pipe run or shell elements to model the surface of the pipe. B31.1 assumes you are calculating the moments in the pipe using beam elements. There are many commercial pipe stress programmes that work with beam elements and work out the flexibili...
Figure 3: Liner elements, nodes, and zones in the 3DEC model.Results and Discussion — Qualitative AssessmentWe confirm that the interface deformation is small relative to the zone deformation (and thus confirm that the elastic interface stiffnesses, kn and ks, are large enough) by ...
The stress values (in kernel and buffer) from the previous simulation calculated on each of the layers’ finite elements are used as the initial values for the new simulation with kernel, buffer and IPyC. By doing this, the thermal strains arising in the next transient will change the ...
