Determination of component and material properties

• Strength behaviour and data for various damage mechanisms
• Forced fracture
• Fatigue
• Wear
• Corrosion
• Thermal loading
• Material properties and modelling for all established strength concepts, also under consideration of environmental conditions (e.g. media, temperature)
• Nominal stress concept
• Local approach concept
• Fracture mechanics concept
• Examples for investigations:
  • Monotonic tensile or torsional tests
  • Fatigue tests with constand or variable amplitude loading (LCF, HCF, VHCF regime)
  • Fracture mechanics tests (fracture toughness, crack resistance curve, crack growth)

Determination of loadings

• Experimental or numerical determination of component loading and deformation in service (e.g. strain measurements)
  • Determination of strains, deformation and stresses (strain gauge measurements, Finite Elements Method)
  • Residual stress measurements
  • Determination of loading (e.g. with calibrated components)
• Derivation of loading spectra
  • Counting algorithms to evaluate time signals (e.g. Rainflow counting)
  • Determination of load spectra and power density spectra
  • Analyzing and preparation of test signals to resuce testing times (e.g. omission techniques)

Component safety analysis and preparation of surveys

• Strength and life calculation based on all established strength concepts
  • Application and verification considering the state of the art or guidelines and rules (e.g. FKM guideline, IIW guideline)
  • Development of new strength calculation methods
• Survey on damage analysis
  • Metallografic and fractografic investigations
  • Determination of damage root
  • Development and experimental verification of improvements
  • Avoidance of damage
• Consulting Services
  • material selection
  • strength optimization
• Technical seminars on strength, material technology and damage analysis
