For the calculation of the experiment in program complex LIRA-CAD a model of orthogonal anisotropy (orthotropy
) in the plate finite elements was implemented.
Moreover, ultrasound propagation paths in directions differing from the main orthotropy
axes (longitudinal L, radial R and tangential T) are significantly shifted from a straight line between the transducers, the actual trajectory being dependent on the local ring and grain angles (Sanabria et al.
The results show a complex interaction between plate orthotropy
and boundary conditions (Baba, 2007).
Identification of plate rigidities of a circular plate with cylindrical orthotropy
using vibration data.
Finally, constitutive models with orthotropy
and bimodularity induced by damage can be proposed in order to evaluate the potentialities in the analysis of reinforced concrete structures.
(1972) demonstrated that the stress distribution of the plate bending specimen was different from a simple beam due to the high orthotropy
of wood materials.
Examples where axial symmetry fails include the crimping of hose assemblies (as a result of gaps between dies) or diaphragms (because of orthotropy
of the reinforcing layer); Fabric-reinforced rubber should consider homogenization schemes based on properties of the yarn and rubber matrix.
Syntactic foams are also a favorite material of pattern makers, since they offer the workability of wood without the orthotropy
caused by a grain.
Additionally, stiffness orthotropy
defined as [K.sub.yy]/[K.sub.xx] was the same for both LOP and LBP, which increased unit loads.
This alloy has moderate initial orthotropy
. To increase the degree of orthotropy
, full size sheets were stretched along the rolling direction up to 3% and 6% of tensile strains.
This is proved by the choice of transverse isotropy hypothesis as induced anisotropy and not the orthotropy
, which would be more natural, but the number of parameters would be excessive to a small benefit.
In order to increase its influence on the eigenfrequencies, the dimension optimization of specimen side aspect ratio and orthotropy
angle is performed.
