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:

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

The current research thrust areas are: multiaxial fatigue of emerging light alloys, fatigue of magnesium (Mg) spot welded joints, cyclic plasticity modeling of wrought alloys, finite deformation, and MEMS failure.
