M. J. Hyder,D. A. Woodford,L. F. Coffinroduces a still unexplored or under-studied theme which is that of the relationship between urban sprawl in its various forms and land quality..The first part of the book is dedicated to the motivations and the theoretical premises from which the research originates, connected to the concept of land

Roy G. Baggerly,Thomas Archboldsted in the present book, a key concept that could be more integrated into policies aimed at achieving more sustainable urban forms is that of quality: a concept that applies to the soil (concerning its intrinsic, therefore biophysical, properties, and its dynamic properties, that is, proper to the

Fatigue Behavior of Ceramics Under Static and Cyclic Loadinges with a longer hold time at maximum stress was comparable with that in static loading. Microstructural analysis suggests that cyclic fatigue mechanisms at both room and high temperatures may invoke the activities behind the crack tip.

Low Cycle Fatigue in WC-Co Cemented Carbides stress amplitudes in comparison with metals. Fatigue life curves are presented in the form of Wöhler and Manson-Coffin curves. Defects in the structure are responsible for the appreciable scatter of the experimental data and represent the sites of fatigue crack initiation.

Thermal Fatigue of an Yttrium-Modified Single-Crystal Superalloy TF. Microprobe analyses have revealed that Y-additions alter the oxide thickness and morphology as well as the distribution of Ni, Cr and Al within the oxide-scale of CMSX-4+Y alloy. Higher oxidation resistance of CMSX-4+Y improves its TF crack initiation life in comparison with SRR99.

Microstructurally-Based Simulation of Multiaxial Low-Cycle Fatigue Damage of 316L Stainless Steel inge deviations from the Miner linear damage cumulative rule which were observed for tension/compression → torsion sequentials tests at 600°C. The scatter as well as the size effects observed in simulated tests can be reprented by a Weibull statistical distribution.

The Effect of Waveform on Low Cycle Fatigue of PCates with fatigue behaviour. This agreement is supposed to explain frequency sensitivity of fatigue crack growth. In fatigue also the damage per cycle depends on a contribution depending on the rate of loading and a contribution due to the time under stress.
