About Course

This webinar is aimed to educate on how to calculate the true-loads involved in your design cylce. Load reconstruction is key factor in estimating accurate stress and strain values. Along with understanding the actual load on the model, Determine optimal strain gauge placement from FEA model, Calculate Load Proportionality Matrices, Use Measured Strains to back calculate Operating loads are key aspects in Durability Assessment. This webinar by Dr. Tim Hunter, Wolf Technologies, USA will cover the aspects of in-situte load measurement and correlations with FEM.


Do you know about your loads ! True-Load does !

True-Load is a first to market to solution that leverages FEA models to place strain gauges on unmodified physical parts and then back calculate loading. Output directly feeds into True-QSE events, a powerful post processing tool that supports rapid virtual iteration. True-Load directly interfaces to FEA fatigue software to make FEA based fatigue with correlated loading events a natural part of the design cycle.

Create multi-channel load cells leveraging your parts and FEA models.

  • Determine optimal strain gauge placement from FEA model
  • Calculate Load Proportionality Matrices
  • Use Measured Strains to back calculate Operating loads
  • Create Quasi-Static Events to be used with True-QSE

One of the most challenging tasks for an analyst is to develop load cases for their FEA model that match measured strain values. Typically, it will take weeks to develop the right load cases that match just one or two strain gauges at a single point in time.

True-Load makes that situation a thing of the past. True-Load will determine optimal gauge placement based on the FEA model. Once strains are collected at these optimal gauge locations, the strain data is read into True-Load to calculate load time histories that will typically match the measured strain to within 2% at every point in time. When combined with True-QSE, interrogating any point in the model for strain, stress or displacement is easy and interactive. Typically, it takes a few minutes to determine the strain gauge placement and a few minutes to back calculate the loading profiles.
