Loading failures

Delayed Failure see under Sustained Load Failure. 

Powders can withstand stress without flowing, in contrast to most liquids. The strength or yield stress of this powder is a function of previous compaction, and is not unique, but depends on stress ap ication. Powders fail only under applied shear stress, and not isotropic load, although they do compress. For a given apphed horizontal load, failure can occur by either raising or lowering die normal stress, and two possible values of failure shear stress are obtained (active versus passive failure). 

Diminution occurred consistently as 1.35-2.1-mm chambers throughout the ancillary structure. Although loss of materials was reasonably uniform in all members, the relative importance of the loss varied significantly as the larval holes crossed areas with low design resistance. At these minimal areas, resistance became equal to static load. Failure occurred as vibrations from a passing helicopter were transmitted through the wall to increase the load beyond resistance. 

Subjected to the same mechanical and thermal loading, failure occurred after 76 min of fire exposure and was triggered by the softening of the upper part of the... 

Sustained Load Failure delayed failure due to the presence of hydrogen in stressed high-tensile steels. 

Hoisting devices have some of the same hazards as other materials handling equipment. Elevated materials can fall on people or items below. Structural failure can occur when loads exceed equipment capacity. Hoisting equipment may become unstable and tip over under certain loading or environmental conditions. Equipment or load failures are likely to cause damage, injury, or death. Operators may have limited visibility and need help to lift and position loads. 

Particular attention must be given to transfer pipework where seam-welded pipe runs are used. In such cases, experience from the American power industry steam reheat line catastrophic failures should be borne in mind. The critical factors identified are weld geometry, weld metal and flux compositions and pipe ovality. Generally, older CRU units utilise seamless pipe in this service but some instances are known, particularly in larger capacity units, where seam-welded pipe is in service. Where necessary, this factor can be taken into account in the assessment procedure described below. Seam welds are subject to the full pressure hoop stress, as well as to many of the system loads. Failure of such a weld is likely to lead to a full-scale rupture, rather than a leak. Accordingly, they must be treated as critical items for assessment, and replacement, rather than repair, should be considered the ultimate outcome. 

A) Lattice boom cranes manufactured after Feb 28, 1992, must be equipped with a device that either automatically prevents damage and load failure from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component), or warns the operator in time for the operator to prevent two-blocking. The device must prevent such damage/failure or provide adequate warning for all points where two-blocking could occur.

Although this may be the design s intent, missing pads may be the result of poor design information or loading failures. These problems can result in nonfunctional designs. 

To have a good load, we should take note about time loading and the quality of loaded products, and eliminate any incompatibilities of products in the same expedition. A Load failure may come from four cases (Flaus and Granddamas, 2002) (Wirth et al., 1996) ... 

Designing with composites, as with any other material, is a combination of art and science. The creative element of the design process is often associated with shape, geometry, colour and surface texture, that is with the visual and tactile attributes of the structure or component. Beneath the surface are the technical aspects of the design the choice of materials, their properties, loads, failure criteria, fabrication and processing methods. 

In most non-ductile frames, however, columns lose the capacity to sustain gravity loads due to shear and subsequent axial-load failures, and as a result, the coUapse mechanism is controlled by the loss in vertical load-bearing capacity. As outlined in Baradaran Shoraka (2013), this type of collapse of older concrete buildings may be precipitated by axial-load failure of coluirms, punching shear failure of slab-column coimec-tions, failure of slab-diaphragm connectitMis, or axial-load failure beam/column joints.
