31Thermo mechanical fatigue — (TMF) is a variation of mechanical fatigue of materials where heating and cooling cycles are applied to a test material additional to a mechanical cyclic loading. The temperature cycles have in most cases the same frequency as the loading cycles …
32Hardness — This article is about mechanical properties of materials. For other uses, see Hard. Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Macroscopic hardness is generally… …
33Nanotoxicology — For the scientific journal of this name, see Nanotoxicology (journal). Part of a series of articles on the Impact of Nanotechnology …
34Thermoplastics — A thermoplastic is a plastic that melts to a liquid when heated and freezes to a brittle, very glassy state when cooled sufficiently. Most thermoplastics are high molecular weight polymers whose chains associate through weak Van der Waals forces… …
35maximum stress — in the testing of the strength of steel a sample is machined into a standard test piece and is stretched in a tensile testing machine until it breaks. The results are expressed in N/mm2 and is the value of the maximum load reached in the test… …
36building construction — Techniques and industry involved in the assembly and erection of structures. Early humans built primarily for shelter, using simple methods. Building materials came from the land, and fabrication was dictated by the limits of the materials and… …
