Our service portfolio in material characterization

Characterization of material behavior

• Yield locus and subsequent yield locus curves (biaxial testing)
• Cyclic tension–compression tests (Bauschinger effect)

• Plastic properties (uniform elongation, strain hardening exponent n, fracture elongation)
• Strength parameters (yield strength, proof strength, tensile strength, compressive strength)
• Stress–strain curves
• Anisotropy parameters according to ISO 10113 (r-values)
• Flow curves

Determination of thermophysical material properties

• Coefficient of thermal expansion
• Thermal diffusivity
• Specific heat capacity
