Experimental evidence that electrical fatigue failure obeys a generalized Coffin-Manson law
Xiangtong He, John Y. Fu
The empirical Coffin-Manson law has been used to characterize the low-cycle mechanical fatigue failure of metallic materials for decades. Our experimental studies reported in this…
Electric-field-induced stress relaxation in alpha-phase poly(vinylidene fluoride) films
Xiangtong He, Shaopeng Pei, Robert E. Baier +1
The relationship between elastic fatigue and electrical cyclic loading in alpha-phase poly(vinylidene fluoride) films has been investigated. Our experimental studies have shown tha…
On the theory of the universal dielectric relaxation
John Y. Fu
Dielectric relaxation has been investigated within the framework of a modified mean field theory, in which the dielectric response of an arbitrary condensed matter system to the ap…
On the physical origin of fatigue phenomena
John Y. Fu
The fractional power-law material behavior has been investigated within the framework of a modified mean field theory, in which high-temperature structure precursors in a crystalli…
On the flexoviscous behavior in viscoelastic materials
John Y. Fu
A phenomenological model on the relationship between viscoelasticity and flexoelectricity is proposed to address the electromechanical coupling under rheological processes in visco…
Gradient scaling phenomenon of piezoelectricity in non-piezoelectric polyvinylidene fluoride films
Sivapalan Baskaran, Xiangtong He, John Y. Fu
It has been well known that flexoelectricity can be exploited to generate an analogous piezoelectric response in non-piezoelectric materials. For the direct flexoelectric effect, t…
Strain gradient induced electric polarization in alpha-phase polyvinylidene fluoride films under bending conditions
Sivapalan Baskaran, Xiangtong He, Yu Wang +1
The relationship between the applied elastic strain gradient and the induced electric polarization in the alpha-phase polyvinylidene fluoride (PVDF) films under bending conditions…
