Structural Mechanics and Materials Laboratory

                              

 

The Structural Mechanics and Materials Laboratory focuses on mechanical testing and computational modeling of structural components and materials used in the Aerospace and Wind Energy industries.

Mechanical Testing can be conducted for full-size structural/components and for materials coupons.

The Lab is divided into two parts:

  •  Structural and component testing
  • Mechanical testing of materials.

A structural testing laboratory is being designed to test wind turbine blades of 5-10 m size for both fatigue and static loading. Measurement equipment includes strain-gage instrumentation and full-field

optical techniques such as 3-D digital image correlation and photoelasticity techniques.

Materials testing capabilities will include a 100 kN servo-hydraulic combined tension-torsion testing machine for fatigue, dynamic and static loading. Fatigue, fracture toughness tests can be conducted in

addition to tensile, compressive and 3-pt bending tests.
