Mpm Validation: Sphere-cylinder Impact Tests: Energy Balance
نویسنده
چکیده
This report discusses the energy balance results observed during the simulation of the impact of an aluminum sphere on an aluminum plate supported by a hollow aluminum cylinder. Due to the high impact velocity, there is considerable ringing of the cylinder which causes the sum of the mechanical energies to increase. An optimal set of input parameters is identified that minimizes ringing and reduces energy increase over the time of the simulation.

We describe ERIT, a collection of C routines for eeciently and reliably handling intersection queries between pairs of primitive objects in 3D. ERIT supports intersection queries between the following pairs of primitives: triangle/line-segment, triangle/triangle, sphere/line-segment, sphere/triangle, cylinder/line-segment, cylinder/triangle, cylinder/sphere, cone/line-segment, cone/triangle, to...
متن کاملDerivation of Specific Heat Rejection Correlation in an SI Engine; Experimental and Numerical Study
The thermal balance analysis is a useful method to determine energy distribution and efficiency of internal combustion (IC) engines. In engines cooling concepts, estimation of heat transfer to brake power ratio, as one of the most significant performance characteristics, is highly demanded. In this paper, investigation of energy balance and derivation of specific heat rejection is carried out e...
متن کاملOptimal Design of Functionally Graded Incompressible Linear Elastic Cylinders and Spheres
We find closed-form solutions for axisymmetric plane strain radial deformations of a functionally graded circular hollow cylinder and radial expansion/contraction of a hollow sphere loaded on inner and outer surfaces by uniform hydrostatic pressures. The cylinder and the sphere are presumed to be made of isotropic and incompressible linear elasticmaterials with the shearmodulus a general functi...
متن کاملUsing the material point method to model chemical/mechanical coupling in the deformation of a silicon anode
The lithiation and delithiation of a silicon battery anode is modeled using the material point method (MPM). The main challenges in modelling this process using the MPM is to simulate stress dependent diffusion coupled with concentration dependent stress within a material that undergoes large deformations. MPM is chosen as the numerical method of choice because of its ability to handle large de...
