Energy conservation in existing buildings deskbook

A accomplished construction power conservation programme, aimed toward lowering power bills by means of over 40%. Designed for engineers and designers, this advisor indicators readers to the various power conservation possibilities to be had this present day, explains tips on how to conscientiously research those possibilities, indicates easy methods to behavior a survey, and describes easy methods to record details.

Elasticity, Fracture and Flow: with Engineering and Geological Applications

During this monograph i've got tried to set out, in as elemen­ tary a sort as attainable, the elemental arithmetic of the theories of elasticity, plasticity, viscosity, and rheology, including a dialogue of the houses of the fabrics concerned and how within which they're idealized to shape a foundation for the mathe­ matical conception.

11 in comparison with HDH materials. The fatigue behavior is enhanced, and wear resistance is excellent. Other titanium alloys have also been shown to exhibit attractive properties fabricated using this new approach (Ref 1, 2) with 10 vol% TiB.

Also, P/M near-net shapes are finding acceptance for pump and valve components in hostile environments. The advantage these parts have compared to closed-die forgings is that they have the same properties as the maximum forged properties in all directions (isotropic), but with inside detail that is not possible with forgings. Also, the delivery time is much shorter for first deliveries for the P/M parts due to much more simplified tooling. HIP cladding of powder materials on solid substrates has become an important engineering technique in a number of applications involving improving corrosion, erosion, and wear properties.
