nowadays, tunneling in urban areas is a common activity for a variety of transportations such as subways, water supply, lifelines andsewers that may require blast operations. the characteristics of stress waves of the blast are quite different from earthquake waves. the blast waves are usually of high frequency content, short duration, equality of amplitudes in horizontal and vertical direction...

The paper focuses on the study of a semi-activated system, based combination two movements forced pitching and free-heaving motion. Therefore, quantifying with accuracy hydrodynamic forces applied hydrofoil seems to be crucial. This is investigated throughout numerical analysis dynamics. deformable structure oscillating in low-Reynolds number flow. In this study, animated by combined heaving co...

Mesh Deformation is an important element of any fluid-structure interaction simulation. In this article, a new methodology is presented for the deformation of volume meshes using incremental radial basis function (RBF) based interpolation. A greedy algorithm is used to select a small subset of the surface nodes iteratively. Two incremental approaches are used to solve the RBF system of equation...

Multi-axis system is constituted by the mechanical links, and the link position load deformations are nonlinear. That is an important factor to affect the positioning accuracy of multi-axis system. As the nonlinear characteristics of link position and load deformations, a novel method for modeling deformations of loaded components based on SVR was presented. The 2R manipulator load deformations...

We have performed ab initio pseudopotential calculations to study the effects of structural deformations of iron porphyrin on the configuration of a carbon monoxide ~CO! attached to it. We have considered two proximal deformations around the heme group: ~i! rotation of a pyrrole ring in the iron porphyrin, and ~ii! rotation of the imidazole side chain bound to the iron atom. We have identified ...

In this paper, we identify and propose solutions for several issues encountered when designing a mesh adaptation package, such as mesh-to-mesh projections and mesh database design, and we describe an algorithm to integrate a mesh adaptation procedure in a physics solver. The open-source MAdLib package is presented as an example of such a mesh adaptation library. A new technique combining global...

Structures of pand sd-shell nuclei are studied with the deformed-basis antisymmetrized molecular dynamics method using the Gogny D1S and Skyrme SLy7 forces as effective interactions. By the energy variation with a constraint, energy curves as functions of quadrupole deformation parameter β are obtained. The energy curves for sd-shell nuclei show structure change as a function of β, and suggest ...
