Evolution of Residual Stress Based on Curvature Coupling in Multi-Roll Levelling

Applied Sciences, 2019
Residual stress is the main cause of flatness defects in sheet metal and the basic method to improve the shape quality of the sheet is to reduce and eliminate the residual stress by multi-roll levelling.

Measurement of residual stress in the brain

Journal of Biomechanical Engineering
ABSTRACT Mechanical stress in brain tissue is an important feature of the brain, likely to play key roles in brain development and brain injury. Here, we characterize residual stresses in grey matter and white matter from the deformed shape of tissue cylinders extracted from the brain using a biopsy needle and imaged with high ...

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Surface micro-morphology and residual stress formation mechanisms of near-net-shaped blade produced by low-plasticity ultrasonic rolling strengthening process

Materials & Design, 2022
Low surface integrity of near-net–shaped (NNS) blades is the primary problem associated with aero engine performance improvements. This paper proposes a low-plasticity ultrasonic rolling strengthening process (URSP) to improve the surface micro ...

A review of residual stress analysis using thermoelastic techniques

, 2009
Thermoelastic Stress Analysis (TSA) is a full-field technique for experimental stress analysis that is based on infra-red thermography. The technique has proved to be extremely effective for studying elastic stress fields and is now well established.

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.

Morphological Evolution of Sn‐Metal‐Based Anodes for Lithium‐Ion Batteries Using Operando X‐Ray Imaging

Advanced Science
Sn‐based electrodes are promising candidates for next‐generation lithium‐ion batteries. However, it suffers from deleterious micro‐structural deformation as it undergoes drastic volume changes upon lithium insertion and extraction.

Basis functions for residual stresses [PDF]

Applied Mathematics and Computation, 2020
We consider arbitrary preexisting residual stress states in arbitrarily shaped, unloaded bodies. These stresses must be self-equilibrating and traction free. Common treatments of the topic tend to focus on either the mechanical origins of the stress, or methods of stress measurement at certain locations.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...
