STUDIES ON THE DEFORMATION OF COMPACTS
… heat flow could occur, energy was dissipated by mechanical hysteresis. thermoelastic aftereffect, and friction at the die wall; rapid recompressive cycles, in a lubricated die, showed only the dissipative effect of mechanical hysteresis. The dependence of energy dissipation characteristics on …

Energy absorption in Ni-Mn-Ga/ polymer composites
… stress-strain loops for Ni-Mn-Ga show a large mechanical hysteresis. This ability to dissipate energy makes this alloys very desirable for damping applications, and by putting particles of Ni-Mn-Ga in a composite, their brittleness becomes less of an issue.

A THREE-DIMENSIONAL FULLY COUPLED HYDRO-MECHANICAL ELASTO-PLASTIC MODEL FOR UNSATURATED SOILS WITH CONSIDERATION OF HYSTERESIS BEHAVIOR
… and/or seasonal wetting-drying cycles. While mechanical hysteresis is a common feature of soils in general, hydraulic hysteresis is associated with unsaturated soils. Most existing constitutive models paid limited attention to the mechanical and hydraulic hysteresis behavior of unsaturated …

Granular Shape Memory Ceramics
… higher critical stresses, and larger mechanical hysteresis loops. These advantages make SMCs attractive for high-output actuation and sensing in extreme environments or energy dissipation applications; however, the key phase transformation generates large stresses and strains that …

A Mechanistic Understanding of the β to α′′ Transformation in Superelastic Ti-24Nb-4Zr-8Sn (wt%)
… in vibration damping systems, due to their wide mechanical hysteresis and large recoverable strains, arising from a re- versible martensitic transformation between a parent bcc β phase and an orthorhombic α′′ martensite. Of these alloys, those based on the Ti–Nb binary system such as Ti2448 …

Characterization and modification of electrospun fiber mats for use in composite proton exchange membranes
… well as the porosity, specific surface area, and mechanical properties of the mat allows one to tailor electrospun mats for specific applications. Despite the widespread and rapidly growing use of electrospinning in the fabrication of novel nanomaterials, there are no simple, universal methods of …

Analýza hysterezního chování vertikálního nastavování světlometu automobilu
Diplomová práce se zabývá vznikem mechanické hystereze u vertikálního nastavovacího mechanismu světlometů automobilu. Nastavovací mechanismus obsahuje určité nepřesnosti, které se ve výsledku můžou projevit jako mechanická hystereze, neboli jev, při kterém se zdroj světla nevrátí do původní polohy …
