A nonlinear dynamic uniaxial strength criterion that considers the ultimate dynamic strength of concrete

International Journal of Impact Engineering, 2017
Abstract The existing test results and semi-empirical equations of the rate-dependent concrete strength have overestimated the actual dynamic strength because they do not distinguish between the actual dynamic strength related to the strain rate effects and the additional resistance caused by inertial effects.

Dynamic Strength Estimates for a High Strength, Experimental Steel

Volume 4: Fluid Structure Interaction, 2005
For several years, the Air Force has been engaged in the development of high velocity air to surface missiles. The objective is to replace larger, high mass weapons with smaller, more versatile projectiles that can achieve the same goals. The reduction of mass requires that the impact velocity be increased to meet the performance requirements. This has

The ‘Liftest’ strength test—an accurate method of dynamic strength assessment?

Clinical Biomechanics, 1986
A technique for the assessment of individual dynamic strength and lifting capacity, known as 'Liftest', has been devised and tested in the USA by Kroemer. We sought to confirm, or otherwise, his estimates of the reliability of the test within sessions, and the applicability of the test in a heavy industry (coal mining). The coefficient of variation for

Relationship of Power to Static and Dynamic Strength

Research Quarterly. American Association for Health, Physical Education and Recreation, 1966
Abstract The purpose of this study was to determine whether static or dynamic leg strength was more related to leg power. Sixty-six male college students were tested for static and dynamic leg strength and leg power. The relationships between leg power and both static and dynamic leg strength were highly significant, but not significantly different ...

Dynamic strength of molecularly bonded surfaces

The Journal of Chemical Physics, 2006
This study reports a theoretical analysis of the forced separation of two adhesive surfaces linked via a large number of parallel noncovalent bonds. To describe the bond kinetics, we implement a three-state reaction model with kinetic rates obtained from a simple integral expression of the mean first passage time for diffusive barrier crossing in a ...

Dynamic strength of materials

Fatigue & Fracture of Engineering Materials & Structures, 1999
The experimental techniques and theoretical background as well as some examples of material strength measurements at submicrosecond load durations are discussed. The presented experimental data for engineering metals and alloys and for metal single crystals demonstrate the effects of material grain structure and temperature on the resistance to high ...
