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.

On the creep characteristics of β-zircaloy

Journal of Nuclear Materials, 1978
Abstract A recent model of creep deformation in pure materials is compared with published data on β-zirconium and β-zircaloy. It is shown that the zircaloys behave like the pure metal in this phase range and that the model is capable of predicting their creep rates to within a factor of 2 on tubing material.

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.

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.

Characteristics and Mechanisms of Clay Creep and Creep Rupture

1992
Abstract Time-dependent deformations, such as creep and secondary compression, and time-dependent stress changes at constant deformation, such as stress relaxation, are important considerations in many geotechnical engineering studies.

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 Tungsten Wires

MRS Proceedings, 1993
AbstractIn this study heavily-drawn tungsten wires were tested for creep at a constant load of 115 MPa in a 10-3 torr nitrogen atmosphere. These fine wires had an elongated rectangular grain morphology with small average grain sizes, 1.6 to 2.2 µm. The typical test sample wire was about 2.54 m long and 130 µm in diameter.

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 ...
