Instron has released a new technical e-guide aimed at helping engineers generate more reliable tensile impact data for materials exposed to rapid loading and high-velocity impact.

The guide, titled “Mastering Impact: A Modern Guide to Tensile Impact Strength Testing With Drop Towers,” explains how dynamic drop testing can improve material characterization and simulation accuracy.

Why High-Strain-Rate Testing Matters

As electric vehicles, lightweight composites and advanced polymer films move into demanding applications, engineers need better data on how materials behave during fast impact events.

This is especially important in:

• EV battery systems
• laminated structures
• thin polymer films
• electronics housings
• structural composites

In these applications, failure can happen within milliseconds.

The Problem With Slow-Speed Data

Traditional tensile testing often uses lower strain rates.

But materials may behave differently under rapid loading, including changes in:

• stiffness
• ductility
• crack growth
• energy absorption
• failure mode

If engineers rely only on quasi-static data, simulation models may depend on extrapolated assumptions.

That can weaken confidence in crash models, safety margins and product validation.

Drop Tower Testing Improves Simulation Confidence

Instron’s guide explains how tensile impact testing with drop towers captures force-time data under realistic loading speeds.

This helps engineers better understand:

• impact energy absorption
• crack development
• strain-rate sensitivity
• lab-to-simulation correlation

Industry Insight

This launch reflects a broader trend in materials engineering: testing methods must now match real application conditions more closely.

For composites, EV materials and lightweight structures, reliable high-strain-rate data is becoming essential for safer design and faster qualification.
