More importantly, the advanced thin-wall energy absorption device can not only improve the passive safety of vehicles, but also open up a new way for lightweight design [4–6]. In addition, the application of new composite materials to thin-walled structures will significantly improve their ...

In order to avoid clogging of the working (filtering) surface of the filter with slag and dross, with the help of MDP excess pressure was created. The value of this pressure makes such height of the rise of the metal in the unheated melting chamber that was higher than the level of ...
applying an MTK barostat50with a time constant of 500 fs to control the pressure at 1 atm. PLUMED51was used to calculate the Pb-I-Pb bond angles during the MD simulation and to add the bias restraint to the I−anions at the bottom of the slab....
has been omitted from the calculation shown in Equation 1. In a particularly preferred aspect of the current invention, the skewness index for the propylene-ethylene copolymer is greater than (−1.2), preferably greater than −1.0, more preferably greater than −0.8, and further more ...
The curves present a similar development trend under axial or eccentric compression with different wall thicknesses. Nevertheless, the ultimate capacity is increased with increasing wall thickness. The load–longitudinal strain curves were derived from the relationship between the load and the average ...
Total pressure: 1.22 MPa Total temperature: 493° K. Wall temperature to total temperature ratio Tw/To: 0.60 Reynolds number based on the distance of the measuring point from the leading edge of the flat plate model: 1.3×107 As can be seen from the characteristics curve of FIG. 15, the...
wall. A theoretical model and a numerical model are established to calculate the sound absorption properties of the metamaterial, which agree well with each other. Based on the sound pressure distribution and energy dissipation obtained from numerical simulation and acoustic impedance analysis, the ...
In the process of bending, the concave side of the tube wall shrinks along the bending direction due to the tangential compressive stress [6], which will inevitably cause an increase in tube wall thickness while the excessive increase will cause wrinkling. Up to now, great efforts have been ...
