Geotechnical Testing Journal, 2020 Abstract A series of undrained cyclic direct simple shear (CDSS) tests on dense Toyoura sand has been performed with the aim to investigate the influence of the stiffness of the DSS device on test results. To this end, springs were installed to reduce deliberately the stiffness of the apparatus.

Modelling strong seismic ground motion: three-dimensional loading path versus wavefield polarization [PDF]
, 2012 Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil.

Cyclic simple shear and triaxial tests on Lisbon Region liquefiable sands
7th International Conference on Earthquake Engineering, 2019 The Lower Tagus River Valley area, in Lisbon, Portugal, has been studied for having a high potential liquefaction risk, due to the geological and geomorphological settings and the seismicity associated to the region. This study focuses on the comparison of the cyclic behaviour of three sands collected on site, using two distinct laboratory procedures ...

Characterization of the material response in the granular ratcheting [PDF]
, 2005 The existence of a very special ratcheting regime has recently been reported in a granular packing subjected to cyclic loading \cite{alonso04}. In this state, the system accumulates a small permanent deformation after each cycle.

The FLC, enhanced fromavbility, and incremental sheet forming [PDF]
, 2009 The FLC is a well known concept in the sheet metal forming world. It is used to map the material’s formability and the make-ability of a product. The FLC is valid only within certain restrictions.

Effects of the Unified Viscoplastic Formulation and Temperature Terms on the Thermomechanical Behavior of Soldering Materials [PDF]
, 2012 Solder materials are critical packaging compounds and due to usually weakest melting temperature among packaging constitutive materials, thus, they are frequently subjected to a multitude of physical phenomena: creep, fatigue and combined hardening ...

Out-of-plane strengthening of slender brickwork masonry partition walls with different types of glass fiber fabrics [PDF]
MATEC Web of ConferencesNon-structural masonry partition wall represents a relatively high risk for the occupants of the building even when subjected to the moderate earthquake loading due to its slenderness and brittle failure.

Passive cyclic pitch control for horizontal axis wind turbines [PDF]
, 1981 A flexible rotor concept, called the balanced pitch rotor, is described. The system provides passive adjustment of cyclic pitch in response to unbalanced pitching moments across the rotor disk.
