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

Conical Test Load Measuring Compressibility

Journal of Geotechnical Engineering, 1993
This is a description of the conical test load (CTL), its concept and special advantages, and describes a case history as example. CTL involves the construction of a cone shaped mound of soil on the ground over a center plate and measuring the settlement of the plate due to the weight of the mound. The advantages of the concept are described.

Reinforcing Loaded Steel Compression Members

Engineering Journal, 1988
Theoretically, it does not seem plausible that a column which is reinforced under load will have the same ultimate capacity as a column reinforced in its unloaded state. Yet there is a tendency to use the allowable stresses for the geometry of the reinforced column for both cases.

Fatigue crack growth under compressive loading

Journal of Nuclear Materials, 1998
S/C magnets have many components which were designed to be compressively stressed. This paper describes a possible fatigue crack growth even under fully compressive stresses. In general crack is thought to close under compressive stress condition.

Lymphatic clearance during compressive loading.

Lymphology, 1982
Lymphatic clearance of radioactive sulfur colloid is measured as a function of externally applied pressure on the hind limb of mongrel dogs. A dead weight device is placed over the site of subcutaneous injection. A solid state Si (Li) is placed into a slot at the bottom of the device to continuously record activity of the tracer.

Failure of compression-loaded multi-directional composite laminates

29th Structures, Structural Dynamics and Materials Conference, 1988
An analytical and experimental investigation of the failure of selected compression-loaded composite laminates is described. A general nonlinear theory is presented for predicting a laminate's compressive strength and failure mode. The theory includes the effects of out-of-plane ply waviness, inplane fiber waviness, and fiber scissoring.

Numerical Investigation of Dynamic Compressive Loading

2008
Three-dimensional (3D) numerical simulations are performed to investigate the mechanical properties of ceramics under impact compressive loading. A microcracking model considering the stochastic distribution of internal defects in ceramics is developed. The deformation and failure process of the ceramic specimen is simulated.

Load‐compression behavior of brittle foams

Journal of Applied Polymer Science, 1970
AbstractQuantitative relationships between the load‐compression behavior and the physical characteristics of the foam matrix, previously reported for flexible systems, have now been extended to brittle foams. The shape of the compression curve is expressed in terms of ψ(ε), a dimensionless function of the compressive strain, while the stiffness, or ...
