i3D Indentation Plastometry as the visual starting point for local material characterization

Material testing solutions

Fast, local mechanical testing in seconds.

With i3D® and Indentation Plastometry, Imprintec makes yield strength, tensile strength and stress-strain curves available directly on critical zones, real parts and small specimens.

Entry paths

Fast material data where the part becomes critical.

With i3D® and Indentation Plastometry, Imprintec makes yield strength, tensile strength and stress-strain curves visible exactly where classical testing routes and tensile testing often become too slow, too global or too expensive: directly on critical zones, real parts and small specimens.

Data depth

Local stress-strain curves, yield strength and tensile strength.

The i3D® data set is used to derive local stress-strain relationships and the corresponding true stress-strain curve. On that basis, local yield strength Rᶦₚ₀.₂, local tensile strength Rᶦₘ and the course of plastic hardening can be derived for the tested zone.

The stress-strain curve is not just a visualisation. It represents a local material statement with direct results for the tested zone: stress-strain curve, Rᶦₚ₀.₂ and Rᶦₘ.

Exactly in small, critical or zone-specific areas, i3D® shows that a local test can deliver mechanical properties directly for the relevant zone.

The figure shows engineering and derived true stress-strain data from one local i3D® test point. From this evaluation, the local stress-strain curve, yield strength Rᶦₚ₀.₂, tensile strength Rᶦₘ and the hardening behaviour of the tested zone are derived.

Why i3D®

Why i3D® matters for development, QA and the lab

i3D® becomes relevant where local material differences drive the decision, timing matters and classical testing chains or tensile testing create unnecessary effort.

Local instead of global

Local yield strength, tensile strength and stress-strain behaviour become accessible exactly where welds, transitions or edge zones make the mechanical difference.

Decide faster

Measurement campaigns, screening and feasibility checks reach a robust technical classification earlier than long, globally oriented testing chains around classical tensile testing.

Less preparation

The effort for specimen logistics, machining and idealised specimen geometry drops significantly when the relevant zone itself should be assessed.

A continuous workflow

Automation, mapping, white light interferometry and inverse evaluation turn the indentation into a documentable testing and decision workflow.

Positioning

Where i3D® has a clear role

Tensile testing remains strong when globally representative, standards-based values from standardised specimens are required. Pure hardness testing remains strong when a fast, established hardness number is enough for comparison or routine QA. i3D® takes its place where small or complex geometries, minimal preparation and local mechanical insight from the relevant zone are what actually matters.

Application insights

Where i3D® becomes technically strong in daily work.

Welds, part testing, screening, inline QA, FEM and cost comparison sorted by the technical starting point of the task.

Critical zones and real parts

Use this group when the real question sits in a weld, a heat-affected zone, a local transition or a geometrically limited component region.

  • local yield strength, tensile strength and flow-stress-strain data instead of a global average only
  • relevant for welds, screws, small geometries and temperature-influenced regions
  • strong when the technical decision depends on the actual local zone

Screening and variant logic

This cluster is relevant when many states, batches or parameter combinations must be ranked quickly before deeper validation starts.

  • compare many variants in a short decision window
  • reduce detours through full classical test chains
  • move faster from ranking to the next sensible validation step

Inline, QA and release logic

Choose these pages when the task is closer to production reality than to a pure laboratory setup and response time matters.

  • supports incoming inspection, QA comparison and release-oriented workflows
  • makes local deviations visible earlier in the process
  • helps connect local material insight with production-near decisions
