Soil Dynamic Constitutive Model for Characterizing the Nonlinear-Hysteretic Response
Characterization of nonlinear hysteretic responses plays a significant role in predicting soil behaviors. They are mostly described with either simple empirical functions or complex constitutive models.

A proposed method to determine in-situ shear modulus and shear strain decay curves in different structured soil [PDF]
This paper illustrates the application of the self-boring pressuremeter test and the seismic dilatometer test to acquire the in-situ decay curves of stiffness with shear strain level (G-γ decay curves) of three types of structural soil, which are granite

Stability of three-dimensional relativistic jets: implications for jet collimation [PDF]
The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale jets are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities.

Timoshenko beam effect in flexural resonant column tests
Abstract Current methods for deriving Young’s modulus (E) from flexural resonant column tests do not account for the Timoshenko beam effect. Hence, the extent of the Timoshenko beam effect is investigated in this study using a series of numerical experiments performed by finite element program LS-DYNA.
