Using Integrated Simulation to Optimize Heavy Equipment Design
Heavy equipment manufacturers want to design products that are durable and perform at their peak under a variety of conditions. To accomplish this, Altair provides an integrated multi-disciplinary simulation environment to virtually test and optimize equipment performance and therefore, help reduce design and development costs. Using simulation-driven design, studying the full dynamics of a product or system is possible, from motion analysis to complete lifecycle durability testing.

Guide to Weld Certification
Welded assemblies are widely used across industrial sectors. The design processes in rail, construction, marine, heavy machinery, pressure vessel construction, and many other industries rely heavily on regulations, codes, and norms such as FKM, DVS-1612, and Eurocode-3.
This guide describes the evaluation and standard based certification of welded constructions by combining CAE methodology with relevant norms and regulations in a guided and standardized workflow.

Altair HyperLife™ – Temperature Influence
The fatigue strength of a material reduces with an increase in temperature. Temperature influence can be accounted by applying the temperature factor Ctemp to modify the fatigue endurance limit FL.
Tips & Tricks
Altair HyperLife™ – Safety Factor Estimation
Safety factor is calculated based on the endurance limit or target stress (at target life) against the stress amplitude from the working stress history. HyperLife calculates this ratio via two criteria’s.
Tips & Tricks
Altair HyperLife™ – Vibration Fatigue
Vibration fatigue analysis can be performed with loading options to predict fatigue in the frequency domain.
Tips & Tricks
Altair HyperLife™ – Modal Superposition
Fatigue analysis can be performed when modal stresses and modal participation factors are available in two different file inputs.Modal stresses are multiplied by modal participation factor, then summed at each point in time. The modal stress file (geometry) is supported for the H3D file format.HyperLife 2020.1 supports OP2 file support for Modal Superposition The supported modal participation factor file formats are PCH and MRF. Currently, only time domain results (from transient analysis) are supported.
Tips & Tricks
Altair HyperLife™ – Damage and Life Results Contour Per Event
Damage and Life contours are available to plot per Event in the Results Explorer. This output is optional and activated in the Preferences dialog.
Output event wise results helps to interrogate the fatigue results to determine which event(s) and subcases are contributing to the fatigue life.
