Finite Element Analysis of Durability and Fatigue Life: Ansys Ncode, Simulia FE-Safe, MSC CAEFatigue

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

The demand for simulation of fatigue and durability is especially strong. Durability often dominates development agendas, and empirical evaluation is by its nature time-consuming and costly. Simulation provides a strategic approach to managing risk and cost by enabling design concepts or design changes to be studied before investment in physical evaluation. The industry-leading fatigue Simulation technology such as Simulia FE-SAFE, Ansys Ncode Design Life and FEMFAT used to calculate fatigue life of multiaxial, welds, short-fibre composite, vibration, crack growth, thermo-mechanical fatigue.

Based on what we want to Design and Analysis, Stress, Strain or temperature from finite element (FE) software such as ANSYS, ABAQUS, NASTRAN, LS-Dyna, MSC Marc etc used. This FEA (Finite Element Analysis) must contain correspond simulation step detail based on what we want to do in Fatigue Simulation. Enteknograte engineers use different methodology for each specific industrial and research fields and multiphysics. MSC CAEFatigue, Ansys Ncode, Simulia FE-Safe and FEMFAT are our fatigue analysis tools. With the Fatigue analysis, we can:
  • Correct for mean stress and surface finish effects
  • Determine a scale or fatigue concentration factor required to achieve a target life
  • Review damage histograms to determine which load cycles were most damaging
  • Output damage time histories to show exactly when the damage occurred

Durability and Fatigue Application highlights in different industry

  •  Aerospace: Wings, panels, engine blades, rivets, bondings, valves, nacelles, interior component, etc.
  • Automotive: Chassis, rivets, bolts, wheels, connecting rods, full body systems, door, seat, dashboard, interior component, drivetrain component, underhood, oil cooler bracket, front-end carrier,Fatigue behavior of vehicle-mounted medical equipment as it interacts with the suspension dynamics of the vehicle and the road load, etc.
  • Biomedical: Prosthesis, Fatigue properties of medical implants, etc.
  • Energy: Pipes, vessel, valves, fan blade, pump body, Effects of the complex conditions seen in wind turbines such as vibration, the effects of rotating components and different wind states, etc.
  • Electronics: Connectors, clips, electronic racks and housing assemblies,etc.
  • Marine and offshore: Ship hulls and staructures fatigue analysis of welded joints using FEA models, etc.
Enteknograte engineers use combination of advanced numerical simulation FEA-CFD tools in conjunction with Fatigue simulation in a variety of industrial applications, including Automotive, Aerospace, Consumer Goods, Heavy Equipment, Marine, Medical Equipment, Off-highway, Offshore, Oil & Gas, Rail, Sporting Goods and Wind Energy:
With our experience in FEA and CFD and using advanced method for Real World Simulation including Fatigue Life and Durability Prediction, Our customers could go beyond over design and minimize the cost and in the same time have a special product with maximum safety factor.

Finite Element based Design and Analysis of Powertrain & Engines

With using FE models of the rotation of crankshafts and the movement of pistons and conrods our engineers can simulate the material property changes for fatigue and creep-fatigue through the engine cycle including complex loading conditions, intermittent contact and complex duty cycles.

Suspension and Chassis

Enteknograte engineers handle complex multiaxial road load data using PSDs, steady state modal and random transient dynamic analyses to calculate the effects of complex vibration fatigue. FE models of large flexible components and structures are analyzed efficiently and special consideration for efficient simulation of  seam welds, structural welds and spot welds, performed in FEA level.


Our engineers can simulate the fatigue life of exhaust components including structural and thermal loading variations and creep and creep-fatigue interaction effects.
