Modeling and analysis of a phase field system for damage and phase separation processes in solids [PDF]

, 2013
In this work, we analytically investigate a multi-component system for describing phase separation and damage processes in solids. The model consists of a parabolic diffusion equation of fourth order for the concentration coupled with an elliptic system ...

A study on the effect of microspheres on the freeze–thaw resistance of EPS concrete

Science and Engineering of Composite Materials
This study investigated the influence of microbead dosages (0, 5, 10, 15, and 20%) on the frost resistance of expanded polystyrene (EPS) concrete. Five groups of EPS concrete specimens were prepared and subjected to rapid freeze–thaw tests.

Mechanical Characterization of a Polymer/Natural Fibers/Bentonite Composite Material with Implementation of a Continuous Damage Model

Applied Sciences, 2023
A characterization of composite materials of a polyester matrix reinforced with natural fibers of Cuban henequen and organophilized Cuban bentonite was carried out, the experimental results of which are used to formulate, implement, and validate a scalar

Gemcitabine, Docetaxel, Melphalan, Carboplatin as Part of Sequential Cycles of High‐Dose Chemotherapy With Autologous Hematopoietic Stem‐Cell Rescue for Multiply Relapsed/Refractory Pediatric Germ Cell Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Although most malignant germ cell tumors (GCTs) are highly curable with cisplatin‐based therapy, options for patients with multiply relapsed/refractory disease remain limited. For this population, we report the first pediatric use of gemcitabine, docetaxel, melphalan, and carboplatin (GemDMC) as part of sequential cycles of high‐dose ...

FE Modeling of Circular, Elliptic, and Triangular Isolated Slabs With a Continuous Damage Model

Frontiers in Built Environment, 2019
The non-linear behavior of reinforced concrete circular, elliptic, and triangular isolated slabs was studied using computational mechanics. Concrete was modeled with a damage model which includes softening, while the behavior of the reinforcing steel was

Incidence and Risk Factors of Serious Osteonecrosis in Pediatric Acute Lymphoblastic Leukemia: A CYP‐C Population‐Based Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteonecrosis (ON) is a debilitating complication of acute lymphoblastic leukemia (ALL) therapy. While numerous studies have explored its incidence and associated risk factors, investigations using large‐scale cohorts remain important to characterize ON across heterogeneous populations.

Predicting the Width of Corrosion-Induced Cracks in Reinforced Concrete Using a Damage Model Based on Fracture Mechanics

Applied Sciences, 2020
Using a finite-element scheme based on a damage model, a numerical system is developed to predict cracks in reinforced concrete beams due to corrosion expansion. The numerical results show that the width of such cracks is affected considerably by (i) the
