Idea mapping is often used in business, engineering, and design, where creativity is essential for success. SCAMPER: SCAMPER is an acronym for the seven different aspects of ideation around which this idea revolves: Substitute, Combine, Adapt, Modify, Put to other uses, Eliminate, and Reverse. By considering each of these elements, in turn, it ...
As the load is increased, a critical value will be reached at which time the crack becomes open. Crack closure occurs from the presence of material propping open the crack faces and can arise from many sources including plastic deformation or phase transformation during crack propagation, corrosion of crack surfaces, presence of fluids in the ...
Compute the change in the free energy (surface energy − elastic energy) as a function of the crack length. Failure occurs when the free energy attains a peak value at a critical crack length, beyond which the free energy decreases as the crack length increases, i.e. by causing fracture. Using this procedure, Griffith found that
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
Courtesy bias, the tendency to give an opinion that is more socially correct than one's true opinion, so as to avoid offending anyone. [137] Groupthink, the psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome.
Innovation may occur due to effort from a range of different agents, by chance, or as a result of a major system failure. According to Peter F. Drucker , the general sources of innovations are changes in industry structure, in market structure, in local and global demographics, in human perception, in the amount of available scientific ...
Brainstorming is a creativity technique in which a group of people interact to suggest ideas spontaneously in response to a prompt. Stress is typically placed on the volume and variety of ideas, including ideas that may seem outlandish or "off-the-wall".
Slow self-sustaining crack propagation known as stress corrosion cracking, can occur in a corrosive environment above the threshold and below . Small increments of crack extension can also occur during fatigue crack growth, which after repeated loading cycles, can gradually grow a crack until final failure occurs by exceeding the fracture ...
