Determination of Some Complex Elastic and Electromechanical Properties of KDP
نویسندگان
چکیده
The described method allows the determination of velocity and attenuation variations introduced by low frequency alternating stresses and electric fields. Uniaxial stress is produced with a high load piezoelectric actuator and controlled with a strain gauge bridge. A modified impulse echo overlap system with a computer controlled sampling oscilloscope permits the measurement of very small effects. Results for Potassium Dihydrogen Phosphate (KDP) near the phase transition at 123 K are presented and discussed.

متن کاملA NEW CEMENT ADDITIVE TO IMPROVE THE PHYSICAL PROPERTIES OF OIL WELL CEMENT AND TO ENHANCE ZONAL ISOLATION
The main purpose of cementing of the well is to provide effective zonal isolation for the entire life of wells. The standard cements cannot prevent loss of zonal isolation when the stress level in the well cement is severely fluctuated. Since elastic cements improve elastic properties, recently, a number of studies have been done in this area. For this purpose, a nanoparticle, named EX-RIPI, wa...
متن کاملCharacterization of piezoelectric materials using ultrasonic and resonant techniques
Resonance technique for determining the physical properties of piezoelectric material can be difficult to implement for some low symmetry systems. Inconstancy may be introduced because several samples are needed and the degree of poling depends on sample geometry. The ultrasonic method on the other hand, allows the determination of a complete set of elastic, piezoelectric, dielectric constants ...

A general initial-boundary value problem of one-dimensional transient wave propagation in a multi-layered elastic medium due to arbitrary boundary or interface excitations (either prescribed tractions or displacements) is considered. Laplace transformation technique is utilised and the Laplace transform inversion is facilitated via an unconventional method, where the expansion of complex-valued...
