LIFE

LIFE is the module for the Fatigue Analysis of structural components.

​

​

Topic addressed:

• Uniaxial and Multiaxial Fatigue

• Strain based Fatigue Analysis

  • Neuber and ESED Glinka methods for elastic-plastic stresses calculation

  • Morrow's, Smith-Watson-Topper, Brown-Miller, Fatemi-Socie, ... Fatigue parameters

  • Multiaxial Proportional and Non-Proportional loadings addressed

• Stress based Fatigue Analysis

  • MMPDS S-N database

  • Standard S-N curves

  • Mean stress corrections with Goodman, Gerber, Soderberg, Haigh, ...

  • Dang-Van, McDiarmid, Carpinteri-Spagnoli methods

  • PSD fatigue with Dirlik method

• Weldings analysis (seam welds and spot welds)

• Virtual strain gauging

• Multiaxial Assessments

GROWTH

GROWTH is the module for Crack Growth analysis in 2D (or quasi-2D) structures.

​

Topics addressed:

• FEM remeshing for propagation of multiple cracks

• Crack stop drill holes

• Stress Intensity Factors calculated with J-integral, Displacement correlation

• Crack kinking captured

• Crack Growth calculated with NASGRO Equation

• NASGRO database provided

• Generalized Willemborg Crack Retardation model integrated

QUICK2DFEM

QUICK2DFEM is a module, not optional, integrated by default in LIFING, solving 2D plane stress or plane strain models created by defining edge geometries and conditions with a simple format.

​

Created models can be used for both Fatigue and Crack Growth assessments.
