RISGenetic Integration of Different Diagnosis Methods and/or Fault Features for Improvement of Diagnosis Accuracy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Genetic integration of different diagnosis methods and/or fault features is proposed in this paper for improvement of diagnosis accuracy, and a weighted matrix is established by integrating neural ...
Mechanically Tunable Solid/Solid Phononic Crystals Through the Rearrangement of Hard Scatterers Controlled by the Deformation of Periodic Elastomeric Matrixes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fixed band gap characteristic of passive phononic crystals (PCs) is possible to limit their applications in engineering. To overcome this shortcoming, inspired by the tunable mechanism of the spider silks, a new class ...
Simulation-Based Unitary Fracking Condition and Multiscale Self-Consistent Fracture Network Formation in Shale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic fracturing (fracking) technology in gas or oil shale engineering is highly developed last decades, but the knowledge of the actual fracking process is mostly empirical and makes mechanicians and petroleum engineers ...
A Reexamination of the Equations of Anisotropic Poroelasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The anisotropic poroelastic constitutive model is reexamined in this article. The assumptions and conclusions of previous works, i.e., Thompson and Willis and Cheng, are compared and clarified. The micromechanics of ...
Theoretical and Numerical Models to Predict Fracking Debonding Zone and Optimize Perforation Cluster Spacing in Layered Shale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shale is a typical layered and anisotropic material whose properties are characterized primarily by locally oriented anisotropic clay minerals and naturally formed bedding planes. The debonding of the bedding planes will ...
Characteristics of Band Gap and Low-Frequency Wave Propagation of Mechanically Tunable Phononic Crystals With Scatterers in Periodic Porous Elastomeric Matrices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of passive responses and fixed band gaps of phononic crystals (PnCs) limit their possible applications. For overcoming this shortcoming, a class of tunable PnCs comprised multiple scatterers and soft ...
Cylindrical Borehole Failure in a Poroelastic Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drilling a cylindrical borehole is the first and important step in oil mining. Borehole design and strength check are big problems of utmost importance. Biot introduced a poroelastic constitutive theory for porous rock ...
Evaluation of the Therapeutic Effect of Bi-Maxillary Osteotomy Using the Stress Distribution on the Temporomandibular Joint When Doing Anterior Teeth Occlusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this study was to investigate how sagittal split ramus osteotomy (SSRO) and Le Fort 1 osteotomy affected the stress distribution of the temporomandibular joint (TMJ) during an anterior teeth bite using the ...
Differential Effects of Isoproterenol on Regional Myocardial Mechanics in Rat Using Three-Dimensional Cine DENSE Cardiovascular Magnetic Resonance
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The present study assessed the acute effects of isoproterenol on left ventricular (LV) mechanics in healthy rats with the hypothesis that β-adrenergic stimulation influences the mechanics of different myocardial regions ...
