The V-notch Charpy impact test, which has been widely used as a pre-qualification test of material toughness, is also used for estimating "fracture mechanics-based toughness of materials".
This method is based on the Weibull stress criterion, in which the Weibull stress at brittle fracture could provide materials constants independent of differences in loading rate and specimen geometry.
This method is based on the Weibull stress criterion, in which the Weibull stress that is influenced by the mechanical and toughness properties of materials is assumed to provide materials constants.
The materials were selected in terms of the yield-to-tensile ratio YR, which exerts a strong influence on crack-tip stress fields.

At present, the materials were mainly focused on semiconductor materials, polymer materials and metal materials.
But these researches were relatively less for metal materials, especially for stainless steel materials.
Before laser processing, the materials should respectively be polished on different SiC papers (800,1200) to eliminate the scratches on the materials’ surface.

The PBF-LB process reduces material wastage as the un-melted powder can be recycled for a later build.
Furthermore, PBF-LB gives the flexibility of combining various materials like glass, metals, and alloys [2].
