Finite Element Analysis of Low Velocity Impact on Carbon Fibers/Carbon Nanotubes Reinforced Polymer Composites

An effort is made to gain insight on the effect of carbon nanotubes (CNTs) on the impact response of carbon fiber reinforced composites (CFRs) under low velocity impact. Certain amount of CNTs could lead improvements in mechanical properties of composites. In the present investigation, ABAQUS/Explicit finite element code (FEM) is employed to investigate various damages modes of nano composites ...

Parallel hp-Finite Element Simulations of 3D Resistivity Logging Instruments

We simulate electromagnetic (EM) measurements obtained by using one transmitter and one receiver antenna in a borehole environment. The measurements are used to assess electrical properties of rock formations. We have started from a problem where logging instruments as well as rock formation properties are assumed to exhibit axial symmetry around the axis of a vertical borehole. The initial com...

Parallel Iterative Computational Methods for 3d Finite Element Flow Simulations

In this paper we discuss sparse matrix computational methods, and their parallel implementations, for evaluating matrix-vector products in iterative solution of coupled, nonlinear equations encountered in finite element flow simulations. Based on sparse computation schemes, we introduce globallydefined preconditioners by mixing clustered element-by-element preconditioning concept with incomplet...

PARALLEL 3D FINITE ELEMENT PARTICLE-IN-CELL SIMULATIONS WITH Pic3P∗

SLAC’s Advanced Computations Department (ACD) has developed the parallel 3D Finite Element electromagnetic Particle-In-Cell code Pic3P. Designed for simulations of beam-cavity interactions dominated by space charge effects, Pic3P solves the complete set of MaxwellLorentz equations self-consistently and includes spacecharge, retardation and boundary effects from first principles. Higher-order Fi...
