Breaching and liquefaction in subaqueous retrogressive flow slides [PDF]

, 2023
Although retrogressive flow slides in subaqueous sandy slopes can be very large and cause substantial damage, the failure mechanisms of such slides are not very clear yet.

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

The Effect of Failure Criteria on Liquefaction and Pore Pressure Prediction in Non-Plastic Soils

Geotechnics
Since the 1960s, cyclic triaxial tests have been utilized to assess the liquefaction susceptibility of cohesionless soils. While standardized procedures exist for conducting cyclic triaxial tests, there remains no universally accepted criterion for ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Cyclic Triaxial Testing: A Primer

J
Cyclic triaxial tests are frequently used in the laboratory to assess the liquefaction susceptibility of soils. This paper will serve a two-fold purpose: First, it will serve to explain how the mechanics of the tests represent the stresses that occur in ...

Influence of unsuitable operational conditions on the transient performance of a small hydrogen liquefier [PDF]

Hydrogen, Fuel Cell & Energy Storage, 2017
Joule-Thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. Although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields.

Development of a flowing-solvent liquefaction apparatus

Fuel Processing Technology, 1990
Abstract A novel, short contact time liquefaction reactor has been developed which combines the advantages of direct, electrical resistance heating of the reactor tube with a constant flow of liquefaction solvent through a fixed bed of coal to remove products from the heated zone. Preliminary results are presented to show the effect of pressure, peak

In situ rheometry of concentrated cellulose fibre suspensions and relationships with enzymatic hydrolysis [PDF]

, 2013
This work combines physical and biochemical analyses to scrutinize liquefaction and saccharification of complex lignocellulose materials. A multilevel analysis (macroscopic: rheology, microscopic: particle size and morphology and molecular: sugar product)

Liquefaction phenomena associated with the Emilia earthquake sequence of May–June 2012 (Northern Italy) [PDF]

Natural Hazards and Earth System Sciences, 2013
In this paper we present the geological effects induced by the 2012 Emilia seismic sequence in the Po Plain. Extensive liquefaction phenomena were observed over an area of ~ 1200 km2 following the 20 May, ML 5.9 and 29 May, ML 5.8 mainshocks; both ...
