Excess pore water pressure generation of loose silty sand under cyclic loading

, 2015
Liquefaction, which may be experienced during earthquakes, blasting, wave loading or sudden static loading, may cause saturated sandy ground to a very soft liquid-like material and many structures upon it sink or tilt, leading to no more use.

A model for excess pore water pressure increment in saturated coral sand considering loading frequency [PDF]

In order to predict the generation characteristics of the excess pore water pressure(ue) in saturated coral sand under different cyclic loading frequencies(), a series of consolidated undrained cyclic triaxial tests are conducted on saturated coral sand ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Effective and neutral stresses in soils using boundary element methods

, 1983
The evaluation of neutral pressures in soil mechanics problems is a fundamental step to evaluate deformations in soils. In this paper, we present some results obtained by using the boundary element method for plane problems, describing the undrained ...

Consolidation behavior of soils subjected to asymmetric initial excess pore pressure distributions with one-way drainage

, 2012
A consolidating clay layer can be singly or doubly drained. The degree of consolidation is a function of the initial excess pore pressure distribution and the drainage conditions.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.
