Finally, the original theory used for Poisson's ratio predication of ordinary anisotropic materials is modified for application to the BWKFs by considering the unique local valley at 45掳 caused by structural differences and possible yarn movements. The modified theoretical equation could exhibit the ...
There are multi interlinked layers of output and inputs. 2.2. PINN for initial/boundary value PDE problem The regular formulation of PINNs, which is depends on the one in [63], is presented in this subsection. Take a look at a compact domain Ω⊂Rn (n>0 is an integer). The ...
specimen's natural frequency of vibration. The Poisson's ratio of the beam can be easily determined after the resonance frequencies of the bending and torsional vibration modes are measured by time-averaged electronic speckle pattern interferometry (TA-ESPI) with the advantages of non- destructive, ...
Finally, the original theory used for Poisson’s ratio predication of ordinary anisotropic materials is modified for application to the BWKFs by considering the unique local valley at 45° caused by structural differences and possible yarn movements. The modified theoretical equation could exhibit the ...
The value of Poisson's ratio is a crucial parameter in rock mechanics and engineering for both intact rock and rock mass. Poisson's ratio has not gotten the attention it merits compared to other essential mechanical characteristics of intact rock and rock mass. Limited relationships exist bet...
We introduce a new multigrid preconditioner for the Poisson problem which can be used with finite element discretisations on general unstructured meshes; this preconditioner is motivated by the fact that the Poisson problem has a condition number which is independent of aspect ratio when Dirichlet ...
A new constitutive equation for solid propellant with the effects of aging and viscoelastic Poisson's ratio is proposed. Effects of thermo-oxidative aging and viscoelastic Poisson's ratio are considered in this comprehensive constitutive equation with two sets of reduced time system coping with the ...
