Forming and Impact Mechanics Research


In a drive to improve fuel-efficiency and reduce vehicle weight, green house emissions and cost; advanced high-strength and light-weight materials are attractive candidates for use in automotive components and structure. However, in order to achieve these objectives while maintaining or enhancing passenger safety, the response of these materials and structures to the gross deformation conditions that occur during manufacturing operations and impact events needs to be better understood.

Research under the direction of Professor Michael Worswick focuses on the characterization and prediction of material behaviour under large plastic strains and/or elevated rates of deformation using a balance of experimental and analytical methods. Recent works and accomplishments include:

  • Experimental and numerical capability for the prediction and characterization of formability during stamping, warm forming, hot stamping, pre-bending and hydroforming of advanced high strength steels, aluminum and magnesium alloys used in light weight automotive structures.
  • Characterization of the crash response of lightweight hydroformed structures fabricated from aluminum alloy and advanced high strength steel tubes
  • Characterization of the high strain rate behaviour of key lightweight sheet materials used by the automotive sector, including magnesium, aluminum, and advanced-/ultra-high strength steel alloys.
  • Experimental and numerical capability for electromagnetic forming of aluminum alloy sheet.
  • Advanced models for localization and fracture used in finite element analysis of impact and forming.
