It was found that the Mott-Grady theory provides reasonably good predictions of the fragment sizes for ductile materials.
Introduction Materials usually break into many fragments under very high strain-rate loadings.
With this method, Hoggatt and Recht[2] obtained the dynamic uniaxial tensile stress-strain data for several ductile materials.
The Mott-Grady theory can provide reasonably close predictions of the fragment size for the ductile materials being tested.

Other than that, borate also one of the most attracting materials and have been studied extensively regarding on the structural properties [4].
Generally, it is found that an excessive doping of emission spectrum ion in inorganic materials could significantly lower the emission intensity.
Hence it can be used for display materials emitting blue color.
