The CoCrFeMnNi high entropy alloys remain an active field over a decade owing to its excellent mechanical properties. However, the application of is limited because relatively low tensile strength. Here we proposed micromechanical model which adopted from theory dislocation density investigate strengthening mechanisms precipitation chromium-rich non-equiatomic alloy. microstructures were obtained directly SEM-BSE images with different annealing temperatures. framework validated by comparing...
A strut-and-tie design methodology is presented for three-dimensional reinforced concrete structures. The unknown model realized through the machinery of a refined evolutionary structural optimization method. Stiffness struts and ties computed from an evolved topology finite element to solve statically indeterminate problems. In addition, compressive strength nodal zones evaluated using Ottosen's four-parameter criterion. Numerical examples are studied demonstrate that proposed suitable...
The application of hydrogels in flexible sensing has received increasing attention, but the simultaneous preparation with good structural stability, strain sensitivity, freezing resistance, and drying resistance remains a challenge. Based on this, GG-nanocellulose/sodium alginate/polyacrylamide composite hydrogel hierarchical network structure was constructed by one-step synthesis incorporating graphene oxide (GO) glycerol into hydrogel. remained structurally intact after 100 compression...
Abstract A simple image‐based method for measuring plane strain fields on the surface of specimens in earthquake engineering experiments was developed. This integrated camera calibration, stereo triangulation, image metric rectification and template matching techniques to develop a that cost‐effective, easy apply provided satisfactory level measurement accuracy. zero‐strain test conducted using this showed accuracy achieved 0.04 pixels. That is, relative displacement 0.005 mm 0.001....
An integrated computational framework was developed in this study for modeling high-intensity focused ultrasound (HIFU) thermal ablation. The temperature field obtained by solving the bioheat transfer equation (BHTE) through finite element method; while, lesion considered as a denatured material experiencing phase transformation and modeled with latent heat. equivalent attenuation coefficient, which considers temperature-dependent properties of target diffraction due to bubbles, proposed...
A three‐dimensional finite element model describing the thermal–mechanical stress distribution in multilayer ceramic capacitors ( MLCC s) during termination firing, soldering, and bending tests is presented. Numerical results indicate that thermal residual stresses originating from soldering process are approximately one‐fifth to half of magnitude flexural at crack occurrence board flex test. The peak tensile numerical simulations correlates with initiation site observed situ tests. effects...
Polymer-mediated lock-and-key assembly via depletion attraction is purely a shape-recognition process without any molecular bonding. Since the relates to osmotic pressure and excluded volume, binding tendency in dispersion of colloids can be controlled by adjusting characteristics polymeric depletants. In this work, dissipative particle dynamics accounting for explicit solvents, polymers, multiple lock-key pairs are performed investigate influences polymer concentration, chain length,...
A novel lightweight Al-Ti-Cr-Mn-V medium-entropy alloy (MEA) system was developed using a nonequiatiomic approach and alloys were produced through arc melting drop casting. These comprised body-centered cubic (BCC) face-centered (FCC) dual phase with density of approximately 4.5 g/cm3. However, the fraction BCC morphology FCC can be controlled by incorporating other elements. The results compression tests indicated that these exhibited prominent strength (~1940 MPa) ductility (~30%)....
The effects of an implant on temperature distribution in a tissue-mimicking hydrogel phantom during the application therapeutic ultrasound were investigated. In vitro experiments conducted to compare influences plastic and metal implants diathermy calibrate parameters finite element simulation models. histories characteristics opaque (denatured) areas phantoms predicted by numerical simulations show good correlation with those observed experiments. This study provides insight into profile...
This paper presents a structural reanalysis method and its applications in optimal design of trusses. technique is derived primarily on the basis reduced formulation, it has several advantages over previous methods. In particular, system uncoupled by using Gram–Schmidt orthonormalization procedure an error measure introduced to adaptively monitor whether good approximate solution achieved. The latter aspect makes this suitable for use problems because changes variables usually vary during...
