A Look Back at a Remarkable Day of Innovation
The 4a Technology Days 2026 brought an impressive mix of international expertise, hands‑on demonstrations, and deep technical insight to the Red Bull Ring in Spielberg. This year’s edition was especially meaningful, as it was held together with AC Styria’s Materials Day, creating a combined platform for materials science, mobility, and simulation technologies.
What followed was two full days of high‑quality presentations, lively discussions, and an inspiring exchange between industry and research.
A Strong Start: Battery Materials, Safety & Characterization
The conference opened with a welcome from M. Schwab (4a engineering) before diving straight into a tightly packed morning focused on battery materials and safety:
- Montanuniversität Leoben kicked things off with an in‑depth look at the characterization of anodes, cathodes, and separators – an area gaining new strategic relevance as industries push for more efficient cell designs.
- PCCL (Polymer Competence Center Leoben) followed with new insights into nano‑indentation as a tool for understanding mechanical behavior at extremely small scales.
- AVL presented critical findings on electric arc formation in lithium‑ion systems, highlighting causes, mitigation approaches, and future research paths.
- Closing the morning block, 4a engineering provided an update on battery abuse characterization and modeling, showcasing how modern testing methodologies regarding thermal runaway connect directly to advanced simulation workflows.
Across all early sessions, one central theme became clear: battery safety is evolving rapidly, and collaborations between universities, technology providers, and industrial partners are accelerating progress.
Automated Material Cards, IMPETUS® & LINOVIS® in Action
After the first coffee break, the focus shifted to material modeling and automated data generation — areas where 4a tools such as LINOVIS® and IMPETUS® and VALIMAT® play an increasingly important role:
- DLR demonstrated how the IMPETUS pendulum tester supports automated calibration of joining connections.
- AIT’s Light Metals Competence Center presented parameter calibration workflows using LINOVIS®, addressing the challenge of efficiently generating accurate GISSMO parameters.
- Sika contributed a highly practical session on adhesive material behavior.
- 4a engineering followed with a broader look at automation in material characterization and modeling especially for highly sophisticated material models such as *MAT_SAMP-1 (*MAT_187) in LS-Dyna – a topic that sparked some of the most active discussions of the day.

Crash Analysis, High Speed Testing & Global Simulation Trends
The afternoon sessions broadened into crash simulation, forming technologies, and high-speed digital capture:
- Husqvarna showed how advanced material identification helps optimize safety helmet shock absorption across temperature extremes.
- JSOL (Japan) provided a detailed view of IMPETUS-based workflows for crash analysis in the automotive sector.
- Fraunhofer IWM introduced new findings on forming speeds and their effects on aluminum sheet energy absorption.
- Ansys discussed an incremental failure model based on LS-DYNA — bridging simulation theory and applied engineering practice.
- Virtual Vehicle then presented a fast-track method for structural assessment.
- Rimac delivered an excellent session on structural foam characterization.
- And finally, Photron closed the day with an impressive demonstration on high-speed volumetric capture, turning fast “moments” into detailed 3D models.
These talks highlighted a clear trend: testing, material science, and simulation are now more intertwined than ever.
