NONCIRCULAR CFRP BICYCLE'S CHAINRING, PART I: STATIC AND LOW-VELOCITY IMPACT ANALYSIS

A Comparison of Low-Velocity Impact and Quasi-Static Indentation

Investigation of Repeated Low Velocity Impact Behaviour of GFRP /Aluminium and CFRP /Aluminium Laminates

The objective of this research was to investigate esponse of repeated low velocity impact tests on glass fibre/ epoxy-Al metal laminates (GEAML) and carbon fibre/ epoxy-Al metal laminates (CEAML) at the same location using drop-weight tester. CEAML, GEAML as well as monolithic Al panels of the same thickness were impacted repeatedly up to four impacts. The effect of repeated impacts on specimen...

load displacement behavior of concrete beam under monotonic static and low velocity impact load

experiments were carried out to observe the influence of loading type on concrete beam specimens. beam specimens made of similar concrete mixture with the same geometry were tested under three point static loading and low velocity drop weight impact loading. load – displacement behavior, absorbed energy dissipation capacity, stiffnesses, failure modes of beam specimens were obtained and discuss...

Influence of noncircular chainring on male physiological parameters in hand cycling.

The purpose of this study was to examine the influence of a noncircular chainring (NCC) compared with a conventional circular chainring (CC) on hand cycling performance. Eleven nondisabled male participants with no hand cycling experience initially completed an incremental exercise test. Afterward, the participants completed two 20 s sprint tests, followed by a 20 min endurance test and then an...

Numerical analysis of low velocity impact on ceramic-metal-composite targets

In the present paper, the problem of low velocity impact of plates made from different configurations of ceramic, aluminum, steel and composite (S-glass polyester) is analyzed numerically using  Abaqus finite element software. The projectile is assumed to be a rigid body with a hemispherical head. Also, for ceramic layers, Holmquist constitutive model, for aluminum and steel layers, Johnson Coo...
