Creep Characteristics of the Human Spinal Column

Orthopedic Clinics of North America, 1975
Thirty-two static compression tests were carried out on 52 intervertebral disks and their posterior articular facet joints. The spinal units were tested within a uniquely designed test apparatus. Following the experiment, each intervertebral disk was examined macroscopically to assess the degree of disk degeneration.

Creep characteristics of piezoelectric actuators

Review of Scientific Instruments, 2000
A major limitation of piezoelectric translator (PZT) actuators is their lack of accuracy originated from the hysteresis and creep. Nevertheless the creep phenomenon is an important factor in many applications of PZT actuators, but it has been investigated less frequently in comparison with the displacement hysteresis.

Characteristics of creep in polycaproamide cloth

Fibre Chemistry, 1998
The applicability of a fast method of determining the creep characteristics by brief measurements, developed for synthetic fibres, to polycaproamide cloth was demonstrated. The advantages of the proposed method are the minimum characteristics used and for this reason, the stability of the numerical values of these characteristics.

Long-term creep and creep rupture characteristics of TiAl-base intermetallics

Materials Science and Engineering: A, 2009
Abstract The present study investigates creep in three TiAl-base intermetallic alloys, Ti–48Al–2Cr–2Nb–1B, Ti–46Al–7Nb–0.6Cr–0.2Ni–0.1Si and Ti–46Al–2W–0.5Si–0.7B (all at.%), in the range of rupture times up to 25 000 h. Creep behaviour of the individual alloys at 1023 K is assessed and compared and reasons for creep strength variations are discussed.

A “characteristic-strain” model for creep

Materials at High Temperatures, 2008
AbstractThe paper describes the construction of a model of creep that is very simple to implement and lends itself to engineering applications for steady or relaxing loads. The model encompasses primary, secondary and tertiary creep behaviour without requiring separate representation of each phase.

Creep characteristics of an experimental model composite

Journal of Strain Analysis, 1974
A simple experimental model is proposed to simulate the creep properties of composite materials with aligned continuous reinforcement. A complete programme of testing, covering the full range of percentage reinforcements at three test temperatures, is described.

Characteristics of interface cracks in creep regime

Materials Science and Engineering: A, 1998
In this study, the growth behavior of interface cracks in bimaterials and in graded/layered materials at creep regime was studied. In the first part of the study, the evolution of the time-dependent stress states ahead of the stationary interface cracks was elucidated using a finite element model.

Stiffness and damping characteristics of aluminum in creep

JOM, 1977
Tensile creep tests conducted at 200 C were performed on annealed commercially pure aluminum specimens in order to measure the dominant elevated temperature dislocation processes. Testing consisted of applying small lateral loads to measure flexural stiffness, and vibrating the specimens laterally in order to measure dynamic modulus and internal ...

Creep characteristics and cavitation mechanisms of AA2017

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications
In this work, the creep behavior of AA2017 and the governing cavitation processes were investigated at intermediate temperatures. Initially, the examined alloy was subjected to solution treatment at 495 °C and then over-aged at 210 °C. Afterward, the creep tests were performed over a temperature range of 120 °C to 210 °C and applied stress in the 120 ...
