A PROGRESSIVE QUADRATIC FAILURE CRITERION FOR A LAMINATE

open access: yesComposites Science and Technology, 1998
The application of failure criteria to laminated composites is a critical step in the determination of the strength and safety of a point in a structure under combined loading conditions. Non-homogeneous stresses within a structure may induce a complicated failure scenario whereby one ply at a point can initiate failure and affect other plies at the ...

The Failure Analysis of Composite Bolted Joint Structure Based on a Nonlinear Model

open access: yesHangkong gongcheng jinzhan, 2019
Composite bolted joints have been widely used in aircraft structures. It is important to study their tensile failure. A three dimensional nonlinear model is established by combining the Hashin’s criterion, energy dissipation rate method, Puck’s criterion

Numerical Analysis of Thermal Shock Cracking Behaviors of Ceramics Based on the Force-Heat Equivalence Energy Density Principle

open access: yesFrontiers in Materials, 2022
Thermal shock is one of the main causes for the fracture of ceramic materials due to their inherent brittleness. Aiming to explore the mechanism of thermal shock cracking behavior of ceramics under different thermal shock conditions, a novel temperature ...

Numerical Analysis of Restrained Continuous Steel Columns under Standard Fire

open access: yesFire, 2023
The steel column performance in realistic structures during a fire has yet to be fully understood because existing research emphasizes single-story performance, thereby disregarding the influence of continuous steel columns in multi-story configurations ...

Uncertainty assessment of onset sand prediction model for reservoir applications

open access: yesCogent Engineering, 2018
Modeling physical systems in engineering always comes with uncertainties in terms of the model’s input parameters. These uncertainties are also present in modeling the onset of sand production, even though considerable effort may be required in ...

Prevalence of 21 Physician‐Defined Severe Toxicities Following Childhood Acute Lymphoblastic Leukemia Treatment: Australian Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...

Sustained Therapeutic Efficacy of Intravenous Plasminogen Concentrate in Pediatric Patients With Type 1 Plasminogen Deficiency: An Analysis of Dosing Parameters and Clinical Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...
