In the same strain rate range, the lower the temperature of the same density foam concrete with sand, the greater the ultimate compressive strength. The change in strength was caused by the presence of pore water or ice in the foam concrete with sand in low-temperature conditions. The ...

where Δv is the potential difference applied to the beam boundaries, α is the thermal expansion coefficient, Kp is the conduction coefficient, and ρ0 is the electrical resistivity. Mechanically, the main structural parameter affecting the stiffness of the inclined beam actuator is the axial force...

It is noted that the reference heat should also be applied from the bottom electrode (via C and D) and the ratio between the HFS signal from the top and bottom heater should be averaged if the EC film thickness is much larger than the thermal diffusion length of the system. Utilizing ...
The strain-energy-density dependence on the volume Full size image 3.2 Need for fiber-reinforced hyperelasticity Consider a square domain expanding horizontally in a volume-preserving fashion (see Fig. 2). How an element deforms, and consequently how the mesh lines change, will depend on how the...
The challenge in accelerometer design is an accelerometer that responds only to acceleration along its sensing axis while rejecting all other mechanical, thermal, and electrical inputs. Pyroshock is a complex environment with acceleration along all axes, large dynamic strain ...
Differential scanning calorimetry (DSC) testing was employed to elucidate the crystal-glass transformation. As depicted in Fig.2d, during the initial up-scan, a notable endothermal peak at 140.7 °C emerges, denoted as the melting temperature (Tm), indicating the transition from a crystalline...
