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.

A New Workflow for Rapid Fatigue Life and Durability Prediction

This session is suited for part-time analysts and simulation experts that want to explore the fatigue life of their latest design, or fatigue simulation specialists interested in seeing the latest fatigue solutions available. Join us and see how Altair HyperLife can enable you to identify potential durability issues, evaluate damage and cycles to failure faster, to ensure durability targets are hit without time-consuming and expensive redesigns.

Webinars

Fatigue Design for Welded Structures

This session is suited for design and engineering teams interested in running fatigue analysis on welded structures. Altair HyperLife gives users the flexibility to run both traditional weld fatigue calculations, and also evaluate welds to specific standards and regulations such as FKM, EC3, and DVS1612. Join us and see how Altair’s solutions can streamline model build for welded structures, quickly enable users to assess weld performance to meet a variety of industry requirements, and avoid costly rework or repairs in later life.

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.

Altair's New, Modern Fatigue Solution: HyperLife

Before a product ever goes to market, companies must understand how their products will behave during and beyond their expected use cycle. Building a brand perception of product quality relies on consistently durable products, regardless of when and where they are produced, time after time. Additionally, high development costs and expensive warranty claims can be mitigated by integrating fatigue simulation into the product development process. There are many tools on the market to simulate the durability and fatigue life of products, but what sets some solutions apart? Learn how HyperLife enables you to differentiate your products through quality and beat competitors to market with quicker engineering decisions.
