Abstract Viscoelastic damping material has been widely used in engineering machinery to absorb vibration and noise. Dynamic behavior of the viscoelastic is mainly affected by temperature frequency. Classical dynamic equations have complex structures with multiple ambiguous parameters. So a novel variable-order fractional constitutive model (VOFC) established based on operator. Then are derived ...

This paper covers the experimental investigation on creep for polypropylene material with constant and varying load conditions. In first condition help of hanger a was applied till specimen breaks in second using tensile helical spring turnbuckle arrangement, reducing respect to time breaks. The subjected 30 Kg at 700c 50Kg 750c. result shows that behavior is significantly dependent phenomenon....

Abstract In metallurgical processes, as for example cold rolling or deep drawing of sheet metal, it is frequently observed that the crystallographic texture, and with anisotropic mechanical properties a material, evolve dynamically. Hence, to describe such necessary model functional dependence material parameters on which itself can vary locally different plastic strain histories. this work, we...
