A phase-field model for mixed-mode fracture based on a unified tensile fracture criterion
Computer Methods in Applied Mechanics and Engineering, 2020 Different fracture patterns can be observed because of different material properties, even the geometry and loading are the same. However, most of the known phase-field fracture models have only considered the tensile failure and may not be directly ...

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Frailty Predicts Incident Osteoporotic Fractures in Veterans with Rheumatoid Arthritis
Arthritis Care &Research, EarlyView.Objective Rheumatoid arthritis (RA) is associated with an increased risk of frailty and osteoporosis, but the relationship between frailty and incident osteoporotic fractures in RA is underexplored. Methods Data were from the Veterans Affairs (VA) Rheumatoid Arthritis Registry. Frailty was measured using the VA Frailty Index (VAFI).

An extended edge-notched disc bend (ENDB) specimen for mixed-mode I+II fracture assessments
International Journal of Solids and Structures, 2020 A new test specimen for mixed-mode I+II fracture studies is proposed. An extended version of edge notch disc bend (ENDB) specimen, which was recently proposed to assess mixed-mode I+III fracture toughness, is designed and developed for introducing ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

On fracture mode partition theories [PDF]
Computational Materials Science, 2012 Abstract Wang and Harvey (2009 and 2010) and Wang and Guan (2010) have developed fracture mode partition theories for one-dimensional fractures in beams and plates based on both classical and shear deformable beam and plate theories. This paper presents comparisons between different theories and numerical simulations to validate the developed ...
