Experimental testing under biaxial loading is generally the appropriate approach for properly evaluating the performance, assisting in the design, and understanding the material behavior of heater head components under complex stress states
We have implanted 76 biaxial total wrist prostheses as a primary procedure in patients with rheumatoid arthritis of the wrist.
It has no cleavage or parting and is biaxial positive, nonpleochroic, and monoclinic.
Liquid crystal researchers did manage to create the biaxial nematic state with complex, soapy mixtures, and with flat molecules tied to a long polymer chain.
The damping functions were obtained by stress relaxation experiments under biaxial , planar and shear deformations.
In buildings, biaxial form offers interesting cantilevering potential.
A limitation in virtually all planar biaxial studies of soft tissues has been the inability to include the effects of in-plane shear.
It's density is near 3.48, and it is biaxial negative.
It is also monoclinic and biaxial positive.
For optical data, the measured 2V of a biaxial mineral can be checked against 2V calculated from the three principal indices of refraction.
