A Large‐Area, Stretchable Accelerometer Array for Spatial Assessment of Chest Compressions in Cardiopulmonary Resuscitation

FlexTech, EarlyView.
A large‐area stretchable accelerometer array enables multi‐point monitoring of chest compression depth and thoracic contour reconstruction during CPR, offering high spatiotemporal resolution for dynamic deformation tracking and providing a new pathway toward intelligent, feedback‐based resuscitation systems. ABSTRACT High‐quality chest compressions are

Experimental study on coupling effects of cyclic confining pressure and intermittent cyclic loading on deformation behavior of saturated soft clay

Yantu gongcheng xuebao
The deformation characteristics of soft clay under intermittent cyclic loading and cyclic confining pressure are studied by conducting two types of cyclic triaxial tests, i.e., continuous cyclic loading and intermittent cyclic loading triaxial tests, and

CYCLIC STRENGTHS OF CLAY AND SAND BY STRAIN RATE CONTROLLED CYCLIC TRIAXIAL TEST

Doboku Gakkai Ronbunshu, 1995
本研究は, 土の載荷速度依存性に着目して, 飽和粘土を主対象に定ひずみ速度繰返し三軸圧縮試験を行い, 従来の応力制御式による繰返し三軸試験結果と比較検討を行ったものである. また, ゆるい飽和砂とまさ土についても同様の検討を行った. その結果, 定ひずみ速度繰返し三軸試験による実験結果は, 特に粘土やひずみ軟化挙動を起こすような緩い砂, あるいは破砕性土であるまさ土などにおいて応力制御試験によるよりも安定した挙動となることが明らかとなった. さらに, 定ひずみ速度繰返し試験により, 粘土の繰返し強度特性におよぼすひずみ速度の影響について調べた.

Toward an idiographic understanding of the role of sleep‐mood dynamics in adolescents' internalizing symptoms

JCPP Advances, EarlyView.
Abstract Background Adolescence is marked by increased vulnerability to sleep disturbances and mood disorders. Understanding how day‐to‐day changes in sleep and mood are linked within the same individual is crucial for clarifying sleep's role in emerging internalizing disorders. However, the extent to which an adolescent's fluctuations in sleep predict

A damage-plasticity model for the dynamic failure of concrete

, 2011
A constitutive model based on the combination of damage mechanics and plasticity is developed to analyse concrete structures subjected to dynamic loading. The aim is to obtain a model, which requires input parameters with clear physical meanings.

A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...
