Strength criteria and slipping planes of anisotropic sand considering direction of major principal stress

Yantu gongcheng xuebao, 2018
The effect of directions of the principal stress on the deformation and strength of sand is due to the anisotropy of soils. The shear strength on a certain plane of the cross-isotropic sand is larger when the angle between this plane and the bedding ...

Formulation of Anisotropic Strength Criterion for Geotechnical Materials

Advances in Civil Engineering, 2020
A new nonlinear unified strength (NUS) criterion is obtained based on the spatially mobilized plane (SMP) criterion and Mises criterion. New criterion is a series of smooth curves between SMP curved triangle and Mises circle in the π plane and thereby ...

Smoothed Podgórski Strength Criterion

IOP Conference Series: Materials Science and Engineering, 2019
Abstract A modification of the Podgórski limit state criterion is proposed in order to smoothen the plasticity surface allowing for application of the yield function in plastic evolution law. Convexity of the potential is discussed and calibration of five material parameters is carried out using common experimental tests, while two ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

An explicit formulation of the macroscopic strength criterion for porous media with pressure and Lode angle dependent matrix under axisymmetric loading

Journal of Rock Mechanics and Geotechnical Engineering, 2021
This paper aims to propose an explicit formulation of the macroscopic strength criterion for porous media with spherical voids. The matrix is assumed rigid and perfectly plastic with yield surface described by the three-parameter strength criterion ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
