RISA Hybrid Molecular Dynamics/Atomic Scale Finite Element Method for Quasi Static Atomistic Simulations at Finite Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a hybrid quasistatic atomistic simulation method at finite temperature is developed, which combines the advantages of MD for thermal equilibrium and atomicscale finite element method (AFEM) for efficient ...
Scalable Hierarchical Parallel Algorithm for the Solution of Super Large Scale Sparse Linear Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The parallel linear equations solver capable of effectively using 1000+ processors becomes the bottleneck of largescale implicit engineering simulations. In this paper, we present a new hierarchical parallel masterslavestructural ...
Mechanics Interpretation on the Bending Stiffness and Wrinkled Pattern of Graphene
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we attempt to answer two questions on graphene from a mechanic's viewpoint: why does this oneatomthick monolayer have finite bending stiffness to ensure its stability? and what is its wrinkle mechanism? As ...
Loading Definition and Design of Bridge Piers Impacted by Medium-Weight Trucks
Publisher: American Society of Civil Engineers
Abstract: Computational simulation was used to investigate the collision process between medium-weight, single-unit trucks and reinforced concrete bridge piers. The simulation results were used to formulate and calibrate a pulse ...
