This review paper presents a methodological study on possible and existing meshfree methods for solving the partial differential equations (PDEs) governing solid mechanics problems, based mainly research work in past two decades at authors group. We start with discussion general steps method nodes, displacements as primary variables. then examine major techniques used each of these steps: (1) displacement function approximations using (2) approximation gradient or strains nodes background...
This paper presents a novel numerical procedure based on the combination of an edge-based smoothed finite element (ES-FEM) with phantom-node method for 2D linear elastic fracture mechanics. In standard method, cracks are formulated by adding phantom nodes, and cracked is replaced two new superimposed elements. approach quite simple to implement into existing explicit programs. The shape functions associated discontinuous elements similar those elements, which leads certain simplification...
The structures of (1−x)PbTiO3–xBiFeO3 (x=0.3 and 0.6) were investigated by means the neutron powder diffraction. A splitting shift between Fe Ti atoms was found along c axis in 0.7PbTiO3–0.3BiFeO3; however, this does not appear 0.4PbTiO3–0.6BiFeO3. tetragonal phase PbTiO3–BiFeO3 exhibits a large spontaneous polarization. negative thermal expansion PbTiO3 is significantly enhanced wide temperature range BiFeO3 substitution. average bulk coefficient 0.4PbTiO3–0.6BiFeO3 a¯v=−3.92×10−5°C−1,...
Abstract Pneumonia is a highly lethal disease, and research on its treatment early screening tools has received extensive attention from researchers. Due to the maturity cost reduction of chest X-ray technology, with development artificial intelligence pneumonia identification based deep learning attracted all over world. Although feature extraction capability strong, existing object detection frameworks are pre-defined anchors, which require lot tuning experience guarantee their excellent...
Abstract Computational modeling is an effective tool for the detection of eye abnormalities and a valuable assistant to hyperthermia treatments. In all these diagnoses treatments, predicting temperature distribution accurately very important. However, standard finite element method (FEM) currently used such purposes has strong reliance on meshes discretized system exhibits so‐called ‘overly stiff’ behavior. To overcome this shortcoming, paper formulates alpha (αFEM) compute two‐dimensional...
The node-based smoothed finite element method (NS-FEM) proposed recently has shown very good properties in solid mechanics, such as providing much better gradient solutions. In this paper, the topology optimization design of continuum structures under static load is formulated on basis NS-FEM. As smoothing domain sub-unit assembling stiffness matrix NS-FEM, relative density domains serves variables. formulation, compliance minimization considered an objective function, and model developed...
Objective: To compare various models of diffusion-weighted imaging including monoexponential apparent diffusion coefficient (ADC), biexponential (fast [D f ], slow s and fraction fast diffusion), stretched-exponential (distributed anomalous exponent term [α]), kurtosis (mean diffusivity mean [MK]) in the differentiation renal solid masses.Materials Methods: A total 81 patients (56 men 25 women; age, 57 years; age range, 30-69 years) with 18 benign 63 malignant lesions were imaged using 3T...
Summary Predicting the frequency response of a complex vibro‐acoustic system becomes extremely difficult in mid‐frequency regime. In this work, novel hybrid face‐based smoothed finite element method/statistical energy analysis (FS‐FEM/SEA) method is proposed, aiming to further improve accuracy ‘mid‐frequency’ predictions. According approach, whole divided into combination plate subsystem with statistical behaviour and an acoustic cavity deterministic behaviour. The treated using recently...
This paper represents some basic mathematic theories for G[Formula: see text] spaces of functions that can be used weakened weak (W 2 ) formulations, upon which the smoothed finite element methods (S-FEMs) and point interpolation (S-PIMs) are based solving mechanics problems. We first introduce prove properties spaces, such as lower boundedness convergence norms, in contrast with H 1 spaces. then equivalence G s norms its corresponding semi-norms. These important essential establishment...
To evaluate the performance of diffusion-relaxation correlation spectrum imaging (DR-CSI) with support vector machine (SVM) in detecting prostate cancer (PCa).In total, 114 patients (mean age, 66 years, range, 48-87 years) who received a MRI and underwent biopsy were enrolled three stages. Thirty-nine assigned for exploration stage to establish model, 18 validation choose appropriate scale mapping 57 test compare diagnostic DR-CSI PI-RADS.In stage, model was established performed better than...
