Material Efficiency in Industry

Material usage optimization has become the cornerstone of the transformation that the industry is currently experiencing. Manufacturers relentlessly pursue lightweight and robust components to deliver cost-efficient production with lower warranties, minimal recall costs, and accelerated timelines. Advanced finite element analysis is a staple in design stress calculations. Many companies still rely on manual stress point selection for spreadsheet analysis to conduct fatigue analysis. This approach is time-consuming and unreliable because it increases the risk of overlooking critical failure locations.

FEA Fatigue Analysis

fe-safe is the technical leader in fatigue analysis software for finite element models. fe-safe has set the benchmark for fatigue analysis software since the early 1990s in close collaboration with the industry. The fe-safe software suite is a world-leading technology for durability analysis from FEA. It directly interfaces with all major FEA suites (Abaqus, ANSYS, Nastran) and can meet the most demanding industry applications.

Fatigue Analysis Methods

fe-safe was the first commercially available fatigue analysis software to focus on modern multiaxial strain-based fatigue methods and it continues to set the benchmark for fatigue analysis software. Extended Packaging includes fe-safe, allowing unified access to all solution technologies within the portfolio through a single token pool. fe-safe is popular for its accuracy, speed, comprehensive capabilities and ease of use. Regardless of the complexity of your fatigue analysis, fe-safe fits smoothly into your design process, enabling you to develop durable products.

Fatigue Analysis Software

The fe-safe suite provides:

  • fe-safe: Accurate, reliable multiaxial fatigue analysis, regardless of the complexity of your loadings and model
  • fe-safe/Rubber: Unique, leading-edge technology for the fatigue analysis of elastomers
  • Verity Module in fe-safe: The original, patented Verity™ Structural Stress Method for seam, structural and spot-welded joints
  • Smooth workflow between the SIMULIA portfolio of products: Abaqus, Isight and Tosca

fe-safe At a Glance

  • Calculates fatigue lives at every point on a model, producing contour plots to reveal fatigue lives and crack sites without missing critical locations.
  • Determines the intensity of stress change required to achieve a target design life. It highlights clearly where the component is under strength and opportunities to save material and weight.
  • Estimates warranty claim curves based on probabilities of failure.
  • Identifies which parts of a duty cycle are most damaging. In prototype testing, this could mean shorter tests with fewer actuators.
  • Accounts for manufacturing effects such as residual stresses from a stamped or formed part,  surface finishes, or the material variation effects in castings and forgings.
  • Automatically detects triaxial stress states, e.g. due to contact, to use more extensive critical plane search
  • Requires no special meshing, allowing for solid and shell elements in the same model.
  • Offers fast random vibration fatigue analysis in the frequency domain via single-channel or multi-channel loading PSDs/CSDs with multi-axial critical plane analysis.
  • Verity in fe-safe includes a unique calculation of the fatigue life of welded joints using the patented VerityTM Structural Stress Method.  It can be used with multi-channel PSD/CSD loading.
  • fe-safe/Rubber includes a unique technology for fatigue of elastomers using state of the art elastomer-specific algorithms.
  • In addition, test signal processing functions and strain gauge fatigue algorithms are included in fe-safe standard.
