In this article, the time-dependent stress redistribution analysis of magneto-electro-elastic (MEE) thick-walled sphere subjected to mechanical, electrical, magnetic and uniform temperature gradient as well as moisture concentration gradient is presented. Combining constitutive equations of MEE with stress-strain relations as well as strain-displacement relations results in obtaining a differen...

The tensile creep and creep-recovery behaviour of a unidirectional SiC fibre-Si3N4 matrix composite was analysed using finite element techniques. The analysis, based on the elastic and creep properties of each constituent, considered the influence of fibre-matrix bonding and processing-related residual stresses on creep and creep-recovery behaviour. Both twoand threedimensional finite element m...

This paper summarizes a cooperative research program between the USDA Forest Service, Forest Products Laboratory (FPL), in Madison, Wisconsin, and Forintek Canada Corp. in Vancouver, British Columbia, Canada. This research program provided detailed creep–rupture and some creep information for composite panel products. Commercially produced plywood, oriented strandboard (OSB), and minimally alig...

Fast-growing poplar wood was modified with low molecular weight ureaformaldehyde resin (UF) at 41.5% concentration or phenol-formaldehyde (PF) at concentrations of 15, 25, and 40%. The physical and mechanical properties were measured, and creep behavior tests were carried out under ambient indoor conditions. The specimens were subjected to 30 and 50% of their maximum bending load. The density, ...

The creep of the pre-strained superalloy N07080 is described in this work. pre-strain was achieved by warm rolling at 1050 oC.-The performed due to additional strengthening, i.e increasing hardness.-The drastically reduces rupture life compared standard heat treated superalloy.-The drastic reductionof result rapid cavity nucleation on stress concentration sites along primary grain boundaries su...

mechanism and factors influencing on creep behavior of clay soil have not been understood yet due to its complex structure. in this paper, to investigate the affecting parameters on the creep behavior of the clay soils such as stress level, over consolidated pressure and water pressure, odeometr test are performed in states of single stage, stepwise and overloaded-unloaded and the creep mechani...
