Stress corrosion cracking ( SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature. SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to a ...
Deformation (engineering) Compressive stress results in deformation which shortens the object but also expands it outwards. In engineering, deformation refers to the change in size or shape of an object. Displacements are the absolute change in position of a point on the object. Deflection is the relative change in external displacements on an ...
A stress ulcer is a single or multiple mucosal defect usually caused by physiological (not psychological) stress which can become complicated by upper gastrointestinal bleeding. These ulcers can be caused by shock, sepsis, trauma or other conditions and are found in patients with chronic illnesses. These ulcers are a significant issue in ...
Abiotic stress. Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way. [2]
A. A shearing force is applied to the top of the rectangle while the bottom is held in place. The resulting shear stress, τ, deforms the rectangle into a parallelogram. The area involved would be the top of the parallelogram. Shear stress (often denoted by τ, Greek: tau) is the component of stress coplanar with a material cross section.
Stressed skin. The Zeppelin-Lindau D.I had stressed skin fuselage and wings. In mechanical engineering, stressed skin is a rigid construction in which the skin or covering takes a portion of the structural load, intermediate between monocoque, in which the skin assumes all or most of the load, and a rigid frame, which has a non-loaded covering.
Social stress can arise from one's micro-environment (e.g., family ties) and macro-environment (e.g., hierarchical societal structure). Social stress is typically the most frequent type of stressor that people experience in their daily lives and affects people more intensely than other types of stressors.
e. In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. [1] [2] For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur ...
