Welcome to the Fatigue and Stress Analysis Lab

Fatigue is the process of progressive localized permanent change occurring in a material subjected to cyclic stresses and strains at some points which may result in crack nucleation and growth to final failure after a sufficient number of fluctuations. Alternations of stress and/or strains are difficult to avoid in many practical engineering situations and are very important in design. In many components such alternating stresses and/or strains are applied in a multiaxial manner with variety of load path patterns including in-and-out-of-phase. This interest has a broad range including automotive, aerospace, off shore structures, power generation, and microelectronics industries. 

The Laboratory for Fatigue and Stress analysis (FATSLAB) is a laboratory in the Department of Mechanical and Mechatronics Engineering with three major goals:

  • Fatigue characterization, modeling and life enhancement.
  • The study and development of the robust and efficient methods for durability analysis and their applications to CAE design.
  • The education of engineering leaders.

The current research thrust areas are: multiaxial fatigue of emerging light materials, durability of advanced joining, soild state additive manufacturing, cold spray coating, cyclic plasticity modeling of wrought alloys.
