چکیده
This paper addresses two important phenomena associated with interpretation of experimental viscoelastic material property data and of direct application to composites. (1) The influences of distinct ramp loading functions and of the rise time to full load on experimental material characterizations are investigated analytically and through numerical simulations and their important contributions to accurate material characterization are evaluated. (2) It is further demonstrated that the determination of relaxation and/or creep functions from the same experimental data in real time is a preferable protocol as it avoids additional unnecessary errors introduced through numerical transform inversions.

متن کاملRheological Response and Validity of Viscoelastic Model Through Propagation of Harmonic Wave in Non-Homogeneous Viscoelastic Rods
This study is concerned to check the validity and applicability of a five parameter viscoelastic model for harmonic wave propagating in the non-homogeneous viscoelastic rods of varying density. The constitutive relation for five parameter model is first developed and validity of these relations is checked. The non-homogeneous viscoelastic rods are assumed to be initially unstressed and at rest....
متن کاملGeneralized Fractional Derivative Anisotropic Viscoelastic Characterization
Isotropic linear and nonlinear fractional derivative constitutive relations are formulated and examined in terms of many parameter generalized Kelvin models and are analytically extended to cover general anisotropic homogeneous or non-homogeneous as well as functionally graded viscoelastic material behavior. Equivalent integral constitutive relations, which are computationally more powerful, ar...
متن کاملA fractional-order model on new experiments of linear viscoelastic creep of Hami Melon
This paper describes our experimental testing of linear viscoelastic creep behaviours in HamiMelon. Experimental data shows that HamiMelon has complex viscoelastic property which cannot be well described by the standard model. Consequently, this study develops a fractional derivative model to describe such complex viscoelastic creep behaviours of Hami Melon. The analytical creep function of the...
متن کاملA Computational study on the effect of different design parameters on the accuracy of biopsy procedure
Needle insertion is a minimally invasive technique in diagnosing and treating tumors. However, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. Therefore, the tissue membrane has to move less to decrease rupturing under the membrane. In this study, the effect of different design parameters on dis...
