ISO 16808 is the test method for determining a biaxial (true) stress-strain curve for metallic sheet and strip using a bulge test with optical measurement. To match this to your program, talk with our team.
What ISO 16808 Covers
It generates biaxial stress-strain data used to calibrate forming and material models for sheet metal, beyond the uniaxial range.
How the Test Is Run
A clamped sheet is bulged by hydraulic pressure while optical systems track the dome shape and strain, and the biaxial stress-strain curve is computed.
Why It Matters
Biaxial data improves sheet-forming simulation accuracy; a bulge fixture and an optical strain-measurement system are essential.
