Horn-loaded compression driver system

The Journal of the Acoustical Society of America, 2006
A horn-loaded compression driver or a loudspeaker has a phasing plug with multiple slots and a common annular chamber. The slots extend from an inlet side to the common annular chamber, which extends to an outlet side. Each slot has a path length extending to a common focal point in the common annular chamber.

Chondrocyte cells respond mechanically to compressive loads

Journal of Orthopaedic Research, 1994
AbstractMany studies have illustrated the effect of mechanical loading on articular cartilage and the corresponding changes in chondrocyte metabolism, yet the mechanism through which the cells respond to loading still is unclear. The purpose of this study was to evaluate the change in shape of chondrocytes under a statically applied uniaxial ...

Secondary Buckling of Compression-Loaded Composite Plates

AIAA Journal, 1996
The phenomenon is described of secondary buckling in plates that are clamped along the loaded edges and simply supported and stiffened along the adjacent unloaded edges. An experiment is described that is used to study secondary buckling of plates with these boundary conditions.

Cervical Injuries Under Flexion and Compression Loading

Journal of Spinal Disorders & Techniques, 1993
Cervical spine segmental tests were performed to determine the specific patterns of initial cervical injury in response to loading just beyond the point of structural failure. Well-defined combinations of flexion rotation and compression translation were applied to segments with varying degrees of disc and facet degeneration.

Analysis of fatigue crack growth under compression–compression loading

International Journal of Fatigue, 2001
Abstract It has been suggested that two driving forces ΔK and Kmax mainly govern the overall fatigue crack growth behavior of any material. This basic concept has been used to explain the damage in the tension–tension and tension–compression regime in a self-consistent manner.

Crack extension under compressive loading

Engineering Fracture Mechanics, 1984
Abstract Non-planar extension (kinking) of a crack subjected to remote biaxial compression is studied to gain insight into compressive failure of brittle solids. Approximate expressions are developed for the stress intensity factors at the tips of the resulting wing cracks.

Compressive Response of Composites Under Combined Fire and Compression Loading

Fire Technology, 2009
The thermal buckling of an axially restrained composite column that is exposed to a heat flux due to fire is studied by both analytical and experimental means. The column is exposed to fire from one-side and the resulting heat damage, the charred layer formation and non-uniform transient temperature distribution are calculated by the thermal model ...

Effects of compressive-compressive loads on spectrum fatigue crack growth

International Journal of Fracture, 1978
Current predictive techniques for crack propagation under cyclic loading rely on the integration of basic constant amplitude growth rate data obtained from laboratory tests on simple coupons. These techniques compute an accumulation of growth under individual loads without regard for load history.

The Fatigue Crack Growth Under Compressive to Compressive Fluctuating Loading

29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 2, 2010
There are some components subjected to compressive and bending loading in ship and offshore structures and fatigue cracks were fond in compressive side of these components caused by fluctuation loadings, during their service. For better understanding the fatigue behavior of these components subjected to compressive to compressive loading, plate ...

Repeated compressive loading of a sand

Canadian Geotechnical Journal, 1979
Twelve repeated load drained triaxial tests to at least 105 cycles on a sand are reported. A threshold stress of about 50% of the static failure strength was found. Below the threshold stress, the permanent deformation and resilient modulus reached constant values. Above the threshold stress, the permanent deformation began to increase rapidly and the
