Strain Field Evolution and Constitutive Model of Coal considering the Effect of Beddings

Lithosphere, 2022
In order to study the bedding effect of coal and rock deformation, the surface deformation fields of coal and rock at different bedding angles were obtained by means of digital image correlation (DIC).

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.

Automated model discovery for human brain using Constitutive Artificial Neural Networks

bioRxiv, 2022
The brain is our softest and most vulnerable organ, and understanding its physics is a challenging but significant task. Massive efforts have been dedicated at testing the human brain, and various competing models have emerged to characterize its ...

A constitutive model for Ti6Al4V considering the state of stress and strain rate effects

Mechanics of materials (Print), 2019
The predictability of manufacturing process simulation is highly dependent on the accuracy of the constitutive model to describe the mechanical behavior of the work material. The model should consider the most relevant parameters affecting this behavior.

Constitutive Model for Reinforced Concrete [PDF]

Journal of Engineering Mechanics, 1995
A numerical model is proposed for reinforced-concrete behavior that combines the commonly accepted ideas from modeling plain concrete, reinforcement, and interaction behavior in a consistent manner. The behavior of plain concrete is govern by fracture-energy-level-based formulation both in tension and in compression.

Supporting Survivor‐Centered Care Through Digital Health Integration

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Survivors of childhood cancer face barriers to receiving guideline‐based, long‐term follow‐up care. Two digital tools, Passport for Care (PFC) and Cancer SurvivorLink (SurvivorLink), address complementary gaps by enabling tailored survivorship care plan (SCP) generation, updating, storage, and sharing.
