Creep and long-term fracture of a narrow rectangular membrane inside a high rigid matrix with proportional dependence on the transverse pressure on time

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
In this work, we studied the creep and long-term fracture of a narrow rectangular membrane in confined conditions (inside a high rigid matrix) with a proportional dependence on the magnitude of transverse pressure on time.

Identification of the continuum damage parameter: An experimental challenge in modeling damage evolution [PDF]

open access: yesActa Materialia, 2012
To accurately predict ductile failures of new advanced metals, continuum damage models (CDM's) require experimental determination of material-specific damage parameter(s). While various experimental techniques are being used to determine these damage parameter(s), possible systematic errors due to methodological difference in damage definition have yet

Dynamic Prediction Model for Initial Apple Damage

open access: yesFoods, 2023
Prediction models of damage severity are crucial for the damage expression of fruit. In light of issues such as the mismatch of existing models in actual damage scenarios and the failure of static models to meet research needs, this article proposes a ...

Correlation of pressure stimulated currents in rocks with the damage parameter

open access: yesAnnals of Geophysics, 2007
Pressure Stimulated Current (PSC) experiments were conducted on marble samples to correlate PSC with the damage parameter, D. The phenomena and procedures taking place in the vicinity of the fracture limit were observed and analytically ...

Intracochlear Recordings of Electrophysiological Parameters Indicating Cochlear Damage [PDF]

open access: yesOtology & Neurotology, 2010
The pathophysiologic mechanisms resulting in hearing loss during electrode implantation are largely unknown. To better understand the functional implications of electrode implantation, we recorded the effects of cochlear damage on acoustically evoked intracochlear measurements using normal-hearing gerbils.

Parameter sensitivities to damage progression

open access: yesStructural Control and Health Monitoring, 2010
SUMMARY Variations in parameters representing natural frequency, damping and effective nonlinearities with fatigue damage are assessed. The experimental system under consideration consists of a steel beam carrying a lumped mass. The identification of the parameters is performed by exploiting and modeling nonlinear behavior of the beam-mass system and ...

The Impact of Damage in Anneling Inconel 718 on Hardness Measured by the Vickers Method

open access: yesFatigue of Aircraft Structures, 2016
In the previous work [1] it was shown that strain hardening had considerable impact on the hardness of Inconel 718. In order to verify the weakening of the material associated with the damage mechanism in the tested material, the hardness tests were ...

The Application of Acoustic Anisotropy to Evaluation of Material Properties

open access: yesFatigue of Aircraft Structures, 2015
Structural properties of materials change under stress, temperature and work environment. These changes are generally unfavorable. They cause a reduction in strength of materials.

Macroscopic Internal Variables and Mesoscopic Theory: A Comparison Considering Liquid Crystals

open access: yesEntropy, 2018
Internal and mesoscopic variables differ fundamentally from each other: both are state space variables, but mesoscopic variables are additionally equipped with a distribution function introducing a statistical item into consideration which is missing in ...

Parameter subset selection in damage location [PDF]

open access: yesInverse Problems in Engineering, 1997
Methods to locate damage in structures, using a finite element model and low frequency measured vibration data, have attracted considerable interest. A large number of parameters are required to ensure that the damage location and mechanism may be modelled by at least one set of parameter values. Generally the identified parameter values are not unique
