Fatigue Analysis and Fracture Mechanics

Fracture mechanics and fatigue analysis are essential to understanding the structural performance of real world materials.  Fracture mechanics is the study of the complex stress field around the tip of a crack and can be used to determine if an existing crack will propagate or arrest.  Fatigue analysis is the study of the fracture behavior under repeated cyclic loading.

FEA Analysis Services

We have years of experience in finite element analysis or FEA that gives us the capabilities and expertise to provide detailed analysis to help our clients predict the fatigue life of materials and determine the likelihood of crack propagation.

Fatigue Testing Process

All materials and equipment over time will at some point be subject to fatigue and break down. Fatigue testing involves the process of taking a sample and applying force in a repeated fashion to see when it will break or how it performs. Materials and equipment are subject to many different applications and environments and require different types of fatigue analyses.

Factors that Cause Fatigue:

  • Temperature
  • Structural Resonance
  • Material Purity

Fatigue Testing and Analysis Program Considerations:

  • Calculate where to apply stress and what type of stress to apply to desired area
  • Calculate the number of cycles that will be applied
  • Calculate the amount of stress that will be applied
  • Determine the applicable safety factor

Once we understand these factors, the experts at Caulfield Engineering can create a custom fatigue and fracture testing analysis for your specific application or environment.
