摘要: Experiments in a laboratory ume indicate that the current velocity necessary to move terebratuloid brachiopod shells is only about one tenth of the velocity required to move pebbles of the same size. Movement of shells is controlled primarily by the relative ease of...
A discrete model for elastic rods undergoing planar motions based on the theory of a directed (or Cosserat) rod is presented. Edge vectors and a director are used to capture cross section deformations including stretch, stretch gradients, shear, shear gradients, and the Poisson effect. In additio...
Complex wrinkle patterns have been observed in various thin film systems, typically with integrated hard and soft materials for various technological applications as well as in nature. The underlying mechanism of wrinkling has been generally understood as a stress-driven instability. On an elastic subst...
This is because many theories underlying the performance of proppant have not been fully understood, such as the theory of proppant embedment and diagenesis, as well as their impact on proppant conductivity performance, which is the current focus of research in proppant studies. This is especially ...
Using shells with a size smaller than their thickness is against the theory and the results may not be reliable. Failure by element erosion was introduced when the damage parameter D in Eq. (5) reached unity at all Gauss points of an element. Fig. 17 illustrates the influence of the mesh...
Bubble pressure and elastic response in helium-irradiated tungsten are systematically investigated in this study. An anomalous shape effect is found that the radial normal stress and mean stress distributions around a nanosized void or bubble are far from the spherical symmetry, which is ascribed to...
Consider an elastic thin film on an elastic compliant substrate, subject to lateral compression. Both the film and the substrate are taken to be linear elastic and isotropic, restricted to small, plane-strain deformation for the present study. Let ε be the nominal compressive strain, relative to...
Shell element of relative degree of freedom (SERDF) is a special kind of solid element, but it can be used in FE analysis of shell structure easily. Its effectiveness and validation in the elastic–plastic stress and dynamic analysis of thin-walled structures have been verified [4]. In ...
