Metallic Materials Biaxial Tensile Test By Using A Cruciform Test Piece

Bidirectional Tensile Testing Machine

→5kN bidirectional tensile testing machine for cruciform specimen, used for bidirectional tensile test of thin metal sheet, to measure the elastoplasticity of metal sheet at fixed stress ratio or strain ratio.

→Orthogonal tensile force of cruciform sample on the plane was 4x5kN, with a constant displacement rate of 0.005-300mm/min and a constant strain rate of 0.0001s-1-0.1s-1. Stress and strain were measured synchronously and continuously.

→The bidirectional tensile stress-strain curve of the cruciform specimen was measured and the plastic work isoline (surface) per unit volume was determined.

Ring Stiffness and Flexibility Testing Machine

→Alternative Test Procedures for Ring Stiffness: use of pipe segments The ring test acc. DIN16917 is carried out with 79° segments, extracted from one pipe. The ring stiffness is defined by measuring of strength and deformation under a constant deformation rate. A pipe segment is used instead on a complete pipe. The pipe segment is deformed vertically under a constant r...
