Fracture toughness and crack-resistance curve behavior in metallic glass-matrix composites [PDF]

open access: yes, 2009
Nonlinear-elastic fracture mechanics methods are used to assess the fracture toughness of bulk metallic glass (BMG) composites; results are compared with similar measurements for other monolithic and composite BMG alloys.

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Study on Elastic-plastic fracture mechanics assessment method of a pipe having multiple circumferential surface cracks for the Rules on Fitness-for-Service of JSME

open access: yesNihon Kikai Gakkai ronbunshu, 2019
This paper describes elastic-plastic fracture mechanics assessment methods of a pipe having multiple circumferential cracks. Ductile fracture strength of a multiple cracked pipe was evaluated using J-integral based on a reference stress method.

Size Effect in Fracture: Roughening of Crack Surfaces and Asymptotic Analysis

open access: yes, 2002
Recently the scaling laws describing the roughness development of fracture surfaces was proposed to be related to the macroscopic elastic energy released during crack propagation [Mor00].

Development of a Disease Model for Predicting Postoperative Delirium Using Combined Blood Biomarkers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Postoperative delirium, a common neurocognitive complication after surgery and anesthesia, requires early detection for potential intervention. Herein, we constructed a multidimensional postoperative delirium risk‐prediction model incorporating multiple demographic parameters and blood biomarkers to enhance prediction accuracy ...

Behaviour of FRP-to-concrete bonded joints [PDF]

open access: yes, 2006
The bond behaviour between FRP (fibre-reinforced polymer) and concrete is a consideration in the design of FRP strengthening mechanisms for structurally deficient or functionally obsolete concrete structures. In the past, a number of empirical models and

Performance Triggered Adaptive Model Reduction for Soil Moisture Estimation in Precision Irrigation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT Accurate soil moisture information is essential for precise irrigation to enhance water use efficiency. Estimating soil moisture based on limited soil moisture sensors is especially critical for obtaining comprehensive soil moisture information when dealing with large‐scale agricultural fields.

Fracture Mechanics of Plate Debonding [PDF]

open access: yesJournal of Composites for Construction, 2008
This paper presents a fracture mechanics model to determine the load at which FRP plates will debond from reinforced concrete beams. This will obviate the need for finite-element analyses to be used in situations where there is an infinite stress concentration and where the exact details of the interface geometry and properties are unknowable.
