Tension testing is not always enough to describe the behavior of a
material; its response to balanced biaxial deformation is
sometimes more critical, and that can be evaluated with the
hydrostatic bulge test. Our expertise in bulge testing covers
-
Standard tests (per ISO 16808 or equivalent) and custom tests in
support of “research & development” efforts
-
Construction of effective biaxial stress/strain curves and
evaluation of material biaxial formability limits
-
Not only balanced biaxial, but also controlled biaxial
deformation to cover several biaxial strain ratios
-
Testing with liquid or gas to accommodate different materials
(metals, composites & polymers) under different conditions
- Quasi-static as well as intermediate rates
- For cold, warm, and hot forming operations
