Sintered neodymium iron boron (NdFeB) is a widely applied permanent magnet, whose
dynamic mechanical properties restrict the further development of its application. In order to …

The brittle fracture may occur in the application of piezoelectric ceramics, but the traditional
research is still limited to the static fracture of the materials. Based on the improved …

With the continuous development of artillery, the disadvantages of hydraulic recoil brakes
gradually appear. At the same time, the appearance of high-performance NdFeB permanent …

Although the force-electricity relationship of piezoelectric ceramics under pulse stress is
found to be nonlinear, there is still lacking a reliable model describing this relationship. To …

Electric fields offer a convenient and tunable way to induce phase transitions for regulating
the electromechanical properties of ferroelectrics. However, regulating the …

The research on the discharge characteristics of PZT under conventional applications has
made good progress. In theory, the piezoelectric equation can be used to describe the …

In order to obtain the stress waveforms of the bubble collapse impact, we chose the pressure
bar method with a high-sensitivity laser transducer to record the stress wave on the rod. The …

This work reports the different solid-state synthesis routes to tune between the A-site and B-
site incorporation of the Bi 2 O 3 additive element in the lead-free Ba 0.85 Ca 0.15 Zr 0.1 Ti …

Compared to a quasistatic environment, the electromechanical response of piezoelectric
ceramics exhibits a considerably nonlinear behavior when subjected to impact. If the effect …

The new-type projectile with the penetration and arson function has been playing an
important role in modern warfare increasingly with new technique development. A new-type …
