51Pantheon, Rome — The Pantheon (Latin Pantheon , [Rarely Pantheum . This rare usage appears in Pliny s Natural History (XXXVI.38) in describing this edifice: Agrippae Pantheum decoravit Diogenes Atheniensis; in columnis templi eius Caryatides probantur inter pauca …
52Resistance welding — refers to a group of welding processes that produce coalescence of faying surfaces where heat to form the weld is generated by the resistance of the welding current through the workpieces. Some factors influencing heat or welding temperatures are …
53Crystallization of polymers — Spherulites viewed between crossed polarizers in an optical microscope. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae,… …
54Extensometer — An extensometer is a device that is used to measure small/big changes in the length of an object. It is useful for stress strain measurements. Its name comes from extension meter . It was invented by Dr. Charles Huston who described it in an… …
55temper brittleness — the loss in impact resistance that is present in some low and medium carbon alloy steels when tempered in the range of 350 deg C 600 deg C. It is revealed by the notched bar impact test but not the tensile test …
56yield point — can be defined as the point where a tensile test piece begins to extend permanently. If the load is reduced to zero, the test piece will not return to its original length …
57yield point — /ˈjild pɔɪnt/ (say yeeld poynt) noun the stress at which an elongation of the test piece of metal in a tensile test first occurs without increase of load. Also, yield stress …

59Lankford coefficient — The Lankford coefficient or R value [Lankford, W. T., Snyder, S. C., Bausher, J. A.: New criteria for predicting the press performance of deep drawing sheets. Trans. ASM, 42, 1197–1205 (1950).] is a measure of the plastic anisotropy of a rolled… …
60ductility — a measure of a material s ability to undergo appreciable plastic deformation before fracture; it may be expressed as percent elongation or percent area reduction from a tensile test. Ductility generally refers to the amount of inelastic… …
