BQCIS

Measuring Toughness and Structural Endurance

Impact and fatigue testing determine how materials perform when subjected to sudden shocks or repetitive cyclic loading. These tests simulate real-world operating conditions to ensure components retain integrity over their service life.

BQCIS provides comprehensive Charpy and Izod impact testing for evaluating material toughness, and high-cycle or low-cycle fatigue testing to assess crack initiation and propagation under cyclic stress.

Our laboratories utilize servo-hydraulic testing systems, instrumented pendulum testers, and strain-controlled fatigue rigs to deliver quantitative, repeatable data for industries including aerospace, automotive, oil & gas, and heavy manufacturing.

Key Activities in Impact & Fatigue Testing

Charpy & Izod Impact Testing

Measurement of absorbed energy to determine material toughness and fracture behavior at various temperatures.

Drop Weight Impact Testing

Evaluation of crack arrest and brittle-to-ductile transition behavior under dynamic loading.

Low-Cycle Fatigue Testing

Simulation of severe cyclic stresses for short-life applications such as welds and pressure components.

High-Cycle Fatigue Testing

Assessment of endurance limits for rotating shafts, fasteners, and structural materials.

Crack Propagation Analysis

Monitoring crack growth rate under cyclic load to predict component life expectancy.

Fracture Toughness (KIC) Testing

Quantifies resistance to crack extension using standardized fracture mechanics methodologies.

Temperature-Controlled Testing

Performs tests under cryogenic or elevated temperatures for service condition simulation.

Digital Data Acquisition

Captures high-speed force, displacement, and strain data for advanced material modeling.

Failure Analysis & Reporting

Providing detailed reports with fractography and microstructural analysis to determine the root cause of failure.

Success Story

Fatigue Life Assessment for Automotive Suspension Systems

The Challenge:

An automotive OEM required fatigue validation of control arm assemblies exposed to repetitive road-induced loads over long-term cycles.

Our Solution:

BQCIS conducted high-cycle fatigue tests up to 10⁷ cycles using servo-hydraulic test frames with real-time deflection monitoring to simulate operational stress patterns.

The Result:

The tested assemblies met endurance requirements with a safety margin of +15%, supporting the OEM’s durability claim and global homologation approval.
