Tests were conducted with tiles impacting on their edge and impacting flat.
More limited improvements were also observed in some of the impacts on flat anvil, although other results indicated to some extent the limitations of the strategy adopted in our research.
Dynamic behaviors of dense granular jets impacting a flat target are experimentally studied and numerically simulated using the Discrete Element Method.
The first consists of a comparison against analytical expressions for post-collision translational and rotational velocities for a single cylinder impacting a flat wall.
But the unemployment rate rose unexpectedly from 6.1%to6.2%2%, while average earnings, a figure carefully watched by the Fed for its inflationary impact, were flat at 2% year on year compared to expectations of 2.3%.
The average impact energy dissipation at the critical velocity (ballistic limit) was 167 J and 121 J for a 4.61 g cm−2 specimen impacted by flat and conically shaped projectiles, respectively.
Last month, the chief judges of 87 federal district courts wrote to Vice President Joseph R. Biden Jr. to express concern over the impact of flat financing for the past few years, followed by nearly $350 million in sequestration cuts that went into effect on March 1.
These algorithms have been validated for single and multiple tablet scenarios: (a) comparing translational and angular velocities of a single bi-convex tablet impacting a flat plane, (b) comparing the fill fractions of bi-convex tablets in a container, and (c) comparing the dynamic angle of repose of bi-convex tablets in a rotating drum.
A theoretical study is performed herein on the perforation of fibre-reinforced plastic laminates subjected to impact by flat-nosed projectiles in a wide range of velocities.
The impact of flat-line funding in the global scale up of antiretroviral therapy (ART) for HIV-infected patients in Africa has not yet been well described.
"I became interested in whether there was a way to convert the impact against a flat object into an impact against an angled object," says Peter Cripton, the mechanical engineer and biomechanics specialist at UBC who led the project.
