This article presents ways to implement a resource-consuming algorithm on hardware with a limited amount of memory, which is the GPU. Numerical integration for higher-order finite element approximation was chosen as an example algorithm. To perform compu- tational tests, we use a non-linear geometric element and solve the convection-diffusion- reaction problem. For calculations, a Tesla K20m graphics...
This paper deals with the optimisation of the joint for thin-walled compressed elementsthat have circular hollow sections (CHS). A steel pipe is studied that has 3 m length,52.3 mm diameter and 3 mm thick wall. Few examples of joint shapes are proposed. Thefirst of them uses two extra plates that are perpendicular to the circular section. They areboth in the shape of an isosceles triangle with 100...
This paper focuses on a comparison of two regularized continuum models for concrete in the simulations of selected benchmarks of response to impact loading. Their overview is performed in the context of application in dynamics. The first one is the Hoffman viscoplastic consistency model, where the strain rate activates regularization. The second model is derived from the scalar damage theory enhanced...
Various methods are available to compute kinematics and dynamics in the case of spa-tial mechanisms. These methods are cumbersome and laborious for large and multibodyspatial mechanisms. The bond graph technique is a powerful alternative tool for mode-ling. A four-link closed-chain 3R2S (3Revolute 2Spherical) spatial mechanism stands outamong the other four-link closed-chain spatial mechanisms due...
