CREEP AND INVERSE CREEP BEHAVIOR OF SILK YARNS

Journal of Macromolecular Science, Part B, 2001
Creep in a polymeric fiber manifests itself as an increase in length under an applied tensile load. During a creep experiment, if the load is reduced, the fiber may show creep recovery rather than a continuing extension under reduced load. This is referred to as inverse creep. The creep behavior of three silk yarns (viz. Muga, Mulberry, and Tassar) has

Creep behaviors of HTPE propellants

Propellants, Explosives, Pyrotechnics, 2023
AbstractIn this paper, creep tests were carried out on HTPE/AP/Al/RDX propellant specimens to investigate the effects of stress level and temperature on their creep behavior and to investigate the creep mechanism. Higher stresses and temperature can cause greater creep strain in the propellant, ultimately leading to its destruction.

Nanoindentation creep behavior of human enamel

Journal of Biomedical Materials Research Part A, 2008
AbstractIn this study, the indentation creep behavior of human enamel was investigated with a nanoindentation system and a Berkovich indenter at a force of 250 mN with one‐step loading and unloading method. A constant hold period of 900 s was incorporated into each test at the maximum load as well at 5 mN minimum load during unloading.

An Investigation on Creep and Creep-Rupture Behaviors of HMPE Ropes

Journal of Offshore Mechanics and Arctic Engineering, 2017
Creep tests of high modulus polyethylene (HMPE) samples are performed to obtain the corresponding creep and creep-rupture curves. The results show that the secondary creep stage is especially pronounced, and its creep rate is nearly constant. Based on this fact, the creep rate at the secondary stage has been utilized as the representative value of each

Rheo-optical Behavior of Polyacrylonitrile: Creep and Creep Recovery

Journal of Applied Physics, 1968
The rheo-optical behavior of PAN homopolymer film has been investigated by means of creep and creep recovery experiments with simultaneous measurements of birefringence changes. Creep experiments were carried out at temperatures of 70°, 100°, 120°, 140°, and 160°C, at a series of stress levels.
