AbstractViscoelastic damage properties of NEPE (Nitrate Ester Plasticized Polyether) solid propellant have been studied in this work. This work focuses on the creep and fatigue damage evolution. Cyclic loading tests for NEPE solid propellants are conducted with different stress ratios.

AbstractThe installation of dense granular columns by various construction techniques can be used to mitigate liquefaction through a combination of densification, increase of lateral stresses, reinforcement, and drainage. The contributing mechanism of shear reinforcement is isolated and explored using nonlinear three-dimensional (3D) finite-element (FE)

Key components of large structures in aeronautics industry are required to be made light and have long enough fatigue lives. It is of vital importance to estimate the fatigue life of these structures accurately. Since the FCG process is affected by various factors, no universal model exists due to the complexity of the mechanisms.

ABSTRACT In order to investigate the dynamic shear characteristics of rubber sand under cyclic loading, a series of cyclic torsional shear tests was conducted using a hollow cylinder torsional shear apparatus. The effects of four cyclic vertical stress ratios (CVSRs = 0.15, 0.25, 0.35, and 0.45) and four cyclic ...

IEEE Transactions on Magnetics, 1996
High purity aluminium used for the stabilisation of superconducting cable achieves very low electrical resistivity at 4.2 K even at high magnetic fields. However, the resistivity is strain dependent, especially cyclic strain dependent. In aluminium stabilised superconducting magnets a strain induced increase of the resistivity can be observed after ...

Cyclic fatigue crack growth in silicon nitride: Influences of stress ratio and crack closure
Acta Metallurgica et Materialia, 1995Abstract The characteristics of cyclic fatigue crack growth was investigated in silicon nitride which hardly shows rising R-curve behavior, using single edge precraked beam specimens. Crack growth behavior is known to be explicable by a power law relationship including both the stress intensity range ΔK and the maximum stress intensity Kmax; i.e.

The characteristics of cyclic fatigue crack growth in a silicon nitride which hardly shows rising R-curve behavior were investigated by using specimens having an indentation-induced flaw. V-shaped behavior was observed in the relation between the maximum stress intensity factor K[sub max] and crack growth rate.
