Metal Forming Research Lab

• Conducts research and experimental testing with the following equipment:
  • 240-ton double action hydraulic press for blanking, piercing, formability testing (Nakazima, Marciniak, Erichsen, bending, hole expansion, hydraulic bulge test), cyclic shear, hot stamping, die wear testing, etc.
     
  • Tension/compression split Hopkinson bar apparatus for high strain rate characterization of work hardening behaviour of metals
     
  • Flat rolling mill for pre-straining up to large deformations
     
  • Instron Charpy impact tester for fracture toughness
     
  • Metallurgical lab, optical microscope, scanning electron microscope 
     
  • FMTI optical strain measurement; high-resolution stereo-cameras; high-speed Photron cameras with digital image correlation software

• Performs Numerical simulations including finite element simulations of various metal forming processes (stamping, drawing, springback prediction, hydroforming, piercing, trimming, electrohydraulic forming etc.) using LS-Dyna or ABAQUS. 

• Development of user-defined material subroutines for ABAQUS allows advanced constitutive models and damage models to be used that are not commercially available.

• Engages in constitutive and damage modeling such as the development of advanced anisotropic, rate-dependent constitutive models and ductile damage models for use in finite element simulations and for prediction of forming behaviour, of the onset of plastic instability and fracture.

• Carries out micromechanical modeling: development of micro- and mesoscale mechanical models (RVE – representative volume element, CA – cellular automata) for prediction of deformation and fracture of multi-phase steel sheets.
