To sum up, it is clearly that ANNs were often used methods in component predictions, because ANNs can deal with more complex problems by making full use of large amounts of data. However, the performance of ANNs is susceptible to hyper-parameters and the scale of dataset, and it is rather...
present an analytical model for the total potential energy, with solutions obtained through an optimization technique, and validate these results against the numerical simulations. Through these analyses, we study the effects of several parameters influencing multistability. Our findings demonstrate that the...
To accelerate the BO process, random feature map32 is employed, which allows us to approximate the Gaussian kernel function with a positive definite symmetric function by probabilistic sampling, and the two hyperparameters in the Gaussian process are automatically determined by maximizing the Type II ...
The three types of unit cells used in this study that represent negative (re-entrant,θ=60∘), near-zero (orthogonal,θ=90∘), and positive (honeycomb,θ=120∘) values of the Poisson’s ratio (a). The other geometrical parameters of the lattice structures are presented in TableS1of...
Electrically conductive roller-compacted concrete (ERCC) is a novel functional material, which can solve the problems of low efficiency of artificial snow removal and deicing on expressway and airport runway and the difficulty in temperature control of dam engineering structures. In this study, we de...
Microstructure, residual stress and thermal history are profoundly affected by laser processing parameters [69]. These parameters (e.g. laser power, laser scanning speed, energy density and hatch distance) can change the shape of melt pools, thermal gradient and cooling rate [70]. Different ...
where parameters A, B, α, and β are constant for a given initial density and strain rate. A is the scaling factor for yield stress; B plays a role of shifting the lower asymptote of the function. And parameters C and γ describe the densification region, varying C implies stretching or...
The static parameters for the fabrication of the combined parts were: (i) Diameter of nozzle: Φ0.3 mm (ii) Diameter of filament: Φ1.75 ± 0.05 mm (iii) Height of layer: 0.27 mm (iv) Default printing layers on the outer periphery: 3 + 3 (by adjusting 3 top and 3 bottom layers)...
