Specific papers explore such aspects as analyzing the corrosion resistance of cast manganese steel by shock excitation and rotation, simulating a fully sintering dental zirconia milling process based on discrete element method, an acoustic emission system for monitoring defects in a hull plate, developing an automatic jet electroplating machining gear tool, and constructing a growth-ability structured model for companies processing agricultural products.
The light from the Veil is probably the result of its ongoing collision with interstellar matter, a process known as shock excitation.
The present study investigates a system comprised of geometrical NES with hysteresis behavior reflecting material nonlinearity and a piezoelectricity-based vibration energy harvester, which is attached to the single-degree-of-freedom primary system under shock excitation. Two configurations of the piezoelectric device, including the piezoelectric element embedded between the NES mass and the structure or ground, are studied through similar methods.
