Enriching constitutive models with meso-scale behaviour: a thermodynamics-based formulation and examples

Open Geomechanics, 2022
A generic approach to encapsulating meso scale details and their associated dissipative mechanisms in constitutive models for geomaterials is presented.

Physics-Based Constitutive Modelling of Ductile Damage and Fracture: A Microstructure-Sensitive Perspective

Metals
Physics-based constitutive modelling remains a cornerstone for predicting ductile damage and fracture in metallic materials, particularly where microstructural mechanisms govern macroscopic response.

Dilatancy Characteristics and Constitutive Modelling of the Unsaturated Soil Based on Changes in the Mass Water Content

Applied Sciences, 2021
Most soil mechanics theories are limited to strain hardening and shrinkage under high compressive stresses, and there are some shortcomings in the selection of suction or degree of saturation as the water content state varies in the constitutive models ...

Constitutive modeling of dispersive mixtures [PDF]

Journal of Rheology, 2001
A rheological model for the stress in liquid-liquid systems is developed based on unifying the theory of the present phenomenological models and by applying a description of the dispersed phase microstructure to remove most of the adjustable parameters present in the theological models.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

An approach to improve the numerical simulation of crushed salt compaction behavior

Frontiers in Built Environment
Crushed salt as backfill material in a repository for high-level nuclear waste is aimed to act as a long-term barrier. The sealing effect of crushed salt evolves with ongoing compaction and therefore reduction in porosity and permeability. For a reliable
