It was found that the critical aerodynamic pressure of piezo-laminated cylindrical panels increases with the increase of surface temperature. Shin et al. [272] used the finite-element method to study the non-li
Example:hydrophone = phased.IsotropicHydrophone(FrequencyRange=[0 1000],BackBaffled=true)creates an isotropic hydrophone element with its frequency range specified between 0 and 1000 Hz. example Properties expand all Unless otherwise indicated, properties arenontunable, which means you cannot change their...
MODELING MAGNETIC MATERIALS FOR FINITE ELEMENT SIMULATION Model of Isotropic Media Isotropic media are considered as a particular case of anisotropic media as described previously. In these materials the magnetic characteristics do not depend on the field direction but only on its strength. In a genera...
The macro- scopic ageing effects are quantified through the evolution of the small-strain shear modulus G0;t during creep under constant pressure. G0;t is determined from shear wave velocity measured by piezo-electric bender elements. The experimental investigation is carried out on natural silica ...
A simplified actuator model that approximates the transducer loading on the structure to a constant pressure load under the array elements is assumed and an optimization problem is set up to compute the excitation voltage and phase of the elements. A five element annular array transducer is ...
(21) The above metric is the one that we use in the junction conditions but due to the nature of the line-element (5), so it is logic to match it with the asymptotic form of line-element (21) which is give by: ds2 ≈ 1 − 2M dt2 − 1 + 2M dr 2 − r 2 dθ 2 +...
various Mn contents have been determined despite the Evolwas held constant at approximately 31.3 and 34.3 Jmm−3, respectively (cf. Table1for processing details). Hence, not only Evolis the factor governing element evaporation. Besides the alteration of the hatch distance, in these cases especiall...
the tensile stress–strain response of solid-state polymer specimens under displacement and stress control, schematically showing the evolution of the stress and strain in each case: (a) Constant strain rate tensile test; (b) stress relaxation at constant strain; and (c) creep at constant stress...
According to the present invention there is provided a porous coal-based material having a density of between about 0.1 g/cm3 and about 0.6 g/cm3 that is produced by the controlled heating of small coal particulate in a “mold” and under a non-oxidizing
1. A powder metallurgically sintered, isotropic permanent magnet having a mean crystal grain size of 1-80 microns and consisting essentially of, by atomic percent, 12-20 percent R wherein R is at least one element selected from the group consisting of Nd, Pr, La, Ce, Tb, Dy, Ho, Er...
