The bottom line is that your granite top could crack and tumble to the kitchen floor with as little as 100 or 150 pounds that s loaded at the center of the 50 inch span.
Tensile strength granite countertop.
Photo courtesy of concrete countertop institute some countertop contractors use other reinforcement materials such as expanded metal and report good results.
Dielectric strength breakdown potential 8 5 kv mm 0 33 v mil.
The bendability tensile strength allows a product to give without breaking.
While i can t say exactly what the tensile strength of your granite top is for its current thickness it s usually only 10 percent of what it exhibits in compression.

The information below gives homeowners an brief overview of the strength attributes of two popular stone types and their respective mohs hardness ratings.
I would not be comfortable with corbels supporting granite marble or any other stone top that extends past 2 3 to sit on.
Ultimate uts 39 mpa 5 7 x 10 3 psi.

You must realize that most if not all stones used for countertops have little to no tensile strength.
But use of carbon fiber has migrated to concrete countertops because it has high tensile strength and is thin enough to fit in tight spots.
