Glass Fractures

What are the different types of glass fractures?

• linear fractures, spiral fractures, and transverse fractures

• tensile fractures, shear fractures, and bending fractures

• compression fractures, torsion fractures, and flexion fractures

• radial fractures, concentric fractures, and cone impact fractures

What is the difference between radial and concentric fractures in glass?

• Radial fractures and concentric fractures are the same thing.

• Radial fractures form straight lines, while concentric fractures form circles around the point of impact.

• Radial fractures radiate outward, while concentric fractures form circles around the point of impact.

• Radial fractures form circles around the point of impact, while concentric fractures radiate outward.
