Studies in Computational Intelligenceas.The parameter, σ., varies with stress and temperature such that p ≃ 4 and Q. for particle-strengthened alloys is equal to the activation energy for creep of the single-phase matrix material. The physical significance of σ. is considered in terms of the mechanisms controlling creep in various stre

Strain controlled tests have been used to determine the influence of strain range, the number of cycles and the dwell period. The implications for structural behaviour and the prediction of stress relaxation are discussed..Some of the tests have been extend

These investigations, however, are almost all concerned with the case of thin shells, and few studies on thick shells are reported except for simple geometry such as cylinders and spheres in spite of their importance in engineering..In the present paper the anal

With some over-simplification they might be labelled as Physical, Phenomenological, Philosophical, Engineering, Computational and Testing approaches, taken in order of presentation. They are all important to the development of our subject and, a

Whilst the Limit Load Reference Stress for a constant moment beam is essentially powerful the paper goes on to bring out its limitations for structures (e.g. a uniform cantilever) where a range of Reference Stresses may be more appropriate than a single stress and for structures which are st

On the basis of the damage summation hypothesis, the integral presentation (3.3) of damage is introduced. Calculating the derivative ω the authors get the kinetic equation for

Ming-Ge Li,Chih-Hung Hsub,Jun-Wei Liuce performed biaxial experiments at continuous linear stress trajectories. To account for creep induced anisotropy tests are made on prestrained specimens subjected subsequently to creep according to another trajectory. The influence of the basic stress invariants as well as the mixed invariants of s
