Sandia’s GeoModel is a generalized plasticity model that was developed primari also applicable to a much broader class of materials such as concretes, ceramics, and even som been incorporated through empirically fitted functions found to be well suited for a wide variety been generalized to include any form of inelastic material response including pore collapse a anisotropy is supported in a li...

Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...

Dynamic response records of pile performance during earthquakes are limited mainly due to the challenges recording seismic soil–pile response. This limitation has led an inadequacy in providing a standardized basis for calibration and validation available analytical numerical methods developed superstructure interaction problems. To bridge this gap, series simulations scaled, shaking table test...

Pile foundations for offshore wind turbines are subjected to large lateral loads. By mounting wings on the perimeter of regular monopiles, winged monopiles have shown better performance in resisting deformation under horizontal loading. However, hazardous effect local scour bearing capacity installed sandy seabed has not been systematically evaluated. In this study, a modified Mohr–Coulomb mode...

The article suggests using a combination of the modified Burgers model and Mohr – Coulomb with degradation adhesion coefficient increase in friction to determine parameters salt rocks. A comparative analysis long-term laboratory tests field observations underground mine workings results obtained calculated certain is carried out. were from statistically processed data tests, determined.

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...
