A new heterogeneous asynchronous explicit–implicit time integrator for nonsmooth dynamics
Computational Mechanics - Tập 60 - Trang 1-21 - 2017
In computational structural dynamics, particularly in the presence of nonsmooth behavior, the choice of the time-step and the time integrator has a critical impact on the feasibility of the simulation. Furthermore, in some cases, as in the case of a bridge crane under seismic loading, multiple time-scales coexist in the same problem. In that case, the use of multi-time scale methods is suitable.

Theory and finite element computations of a unified cyclic phase transformation model for monocrystalline materials at small strains
Computational Mechanics - Tập 40 - Trang 429-445 - 2006
After a survey the refined numerical treatment and verification is presented for a rate-independent macroscopic unified PT material model (including mass conservation with respect to phase fractions and covexified free energy) by Govindjee and Miehe (Comput Methods Appl Mech Eng 191:215–238, 2001) for describing SME and SE effects within a linear kinematic setting. Special attention is given to te...... hiện toàn bộ

Computational Mechanics - Tập 66 Số 4 - Trang 877-891 - 2020
Numerical modeling of shape memory alloy linear actuator
Computational Mechanics - Tập 56 - Trang 443-461 - 2015
The demand for shape memory alloy (SMA) actuators in high-technology applications is increasing; however, there exist technical challenges to the commercial application of SMA actuator technologies, especially associated with actuation duration. Excessive activation duration results in actuator damage due to overheating while excessive deactivation duration is not practical for high-frequency appl...... hiện toàn bộ
Linear and Geometrically nonlinear analysis of plates and shells by a new refined non-conforming triangular plate/shell element
Computational Mechanics - Tập 36 - Trang 331-342 - 2005
A refined non-conforming triangular plate/shell element for linear and geometrically nonlinear analysis of plates and shells is developed in this paper based on the refined non-conforming element method (RNEM). A conforming triangle membrane element with drilling degrees of freedom in Cartesian coordinates and the refined non-conforming triangular plate-bending element RT9, in which Kirchhoff kine...... hiện toàn bộ
Large eddy simulation of a horizontal particle-laden turbulent planar jet
Computational Mechanics - Tập 27 - Trang 128-137 - 2001
Numerical simulations of the particle-vortex interactions for an unforced, incompressible, spatially developing horizontal particle-laden turbulent planar jet are reported. Effects of the initial two-phase velocity slip on the instantaneous concentration distribution of particles with and without the influence of gravity are studied. Continuous phase simulation is performed by the method of large...... hiện toàn bộ
Efficient implementation of a generalized Cholesky factorization for Symmetric Galerkin Boundary Element Methods
Computational Mechanics - Tập 32 Số 4-6 - Trang 362-369 - 2003
Analysis of laminated composite beams and plates with piezoelectric patches using the element-free Galerkin method
Computational Mechanics - Tập 29 - Trang 486-497 - 2002
An efficient meshfree formulation based on the first-order shear deformation theory (FSDT) is presented for the static analysis of laminated composite beams and plates with integrated piezoelectric layers. This meshfree model is constructed based on the element-free Galerkin (EFG) method. The formulation is derived from the variational principle and the piezoelectric stiffness is taken into accou...... hiện toàn bộ
Master-master frictional contact and applications for beam-shell interaction
Computational Mechanics - Tập 66 - Trang 1213-1235 - 2020
The surface-to-surface master–master contact treatment is a technique that addresses pointwise contact between bodies with no prior election of slave points, as in master–slave case. For a given configuration of contact-candidate surfaces, one needs to find the material points associated with a pointwise contact interaction. This is the local contact problem (LCP). The methodology can be applied t...... hiện toàn bộ
Computational modeling of gas-surface interaction
Computational Mechanics - Tập 15 - Trang 224-232 - 1994
In this study, a new computational modeling of the gas-surface interaction is proposed to explain the results of the scattering experiments of molecular beams from solid surfaces, especially from industrial surfaces. The characteristic feature of the model is to settle the adsorbed gas layer and the collision layer which involve adsorbed molecules and surface molecules, respectively. Incident mole...... hiện toàn bộ
