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
