ProSIM has very high level of expertise in the areas of numerical simulation of fatigue, fracture and durability. Complex duty cycle loads / service loads are accounted in computer simulation to predict:
- Crack initiation in Multi-Axial fatigue
- Thermo-mechanical fatigue
- Creep
- Creep – Fatigue interaction
- Use strain based or stress based algorithms
- Crack propagation to failure
- Estimate the stress intensity factors
- Fatigue of welded structures
ProSIM has applied these in the automotive, aerospace, power plants, and other verticals for
- Durability based design
- Damage tolerant design
- Remaining life assessment and extension
- Failure analysis by running simulation of multiple, what-if scenarios, to predict the root cause of failure.
Some of the projects ProSIM has undertaken in the area of fatigue and fracture are:
- Thermo-mechanical fatigue of crank shaft, cylinder head, cylinder line
- Fatigue failure of stabilizer bar
- Durability based, simulation driven design of steering system components
- Fatigue of automotive wheels (LCV,HCV, Passenger cars, forged, cast, aluminum and steel)
- Creep fatigue analysis of ligament cracks in thermal power plants
- Fatigue failure rotor discs of gas turbines
- High temperature fatigue failure of turbine blades
- Fatigue failure of VT fuselage lug joints
- Crack propagation of air craft turbine discs
- Fatigue failure analysis of propeller shaft
- Crack propagation through sandwitched plate
- Fatigue and fracture of riveted holes in air craft structure
