Impact

What Is Impact Testing?

Impact testing measures the amount of energy a material absorbs when it is fractured by a sudden удар. Unlike slow, static mechanical tests, impact testing reflects real service conditions where loads are applied rapidly.

Common impact testing methods include:

Charpy impact test
Izod impact test

These methods differ in specimen geometry and loading configuration but share the same goal: assessing resistance to sudden fracture.

What Impact Testing Measures

Impact testing provides information on:

Impact energy absorption
Material toughness
Brittle vs. ductile fracture behavior
Temperature-dependent impact performance
Sensitivity to notches and stress concentrators

Results are especially valuable for identifying materials that may appear strong in static tests but fail catastrophically under impact.

Why Impact Testing Matters

Impact-related failures can lead to:

sudden cracking or breakage
loss of structural integrity
safety hazards
unexpected product failure in service

Impact testing helps you:

evaluate suitability for dynamic or shock-loaded applications
compare materials, grades, or suppliers
identify brittle behavior at low temperatures
validate processing, heat treatment, or formulation changes
support failure investigations involving sudden fracture

Typical Application Scenarios

Metals & Alloys

Toughness evaluation of steels and alloys
Heat treatment and welding qualification
Low-temperature performance assessment

Plastics & Polymers
