Bone Cement Four-Point Bending Fatigue Tester
Category：Other
Introduction
Product Introduction:
The Bone Cement Four-Point Bending Fatigue Tester is designed to evaluate the fatigue performance of acrylic resin bone cements under quasi-static and cyclic loading. It simulates physiological conditions using an integrated thermostatic water bath and provides precise measurements of fatigue life, crack propagation, and S-N curves, enabling comprehensive mechanical assessment of bone cement materials used in orthopedic applications.
Application Scope:
This tester is suitable for testing acrylic bone cements used in orthopedic implants, including hip and knee arthroplasty. It can accommodate rectangular beam specimens ranging from 2×4×30mm to 6×12×60mm and is applicable for both research laboratories and medical device manufacturers.
Applicable Standards:
YY/T 1429 (China): Four-point bending fatigue of bone cements
ISO 16402 (International): Fatigue life determination of bone cements in simulated physiological environments
ASTM F2118: Constant load fatigue testing of polymer-based bone cements
Product Advantages:
Dual-Environment Testing: Simulates in-vivo conditions with a 37°C ±0.5°C thermostatic water bath for clinically relevant results.
Precision Fatigue Analysis: Frequency range from 0.01Hz to 50Hz captures both low-cycle and high-cycle fatigue behavior.
Automated SOP Execution: Pre-loaded YY/T 1429 and ISO 16402 protocols ensure compliance.
Real-Time Monitoring: Acoustic emission sensors detect crack initiation and allow live S-N curve plotting.
Modular Specimen Clamping: Quick-release fixtures for efficient specimen installation and consistent results.
Data Integrity: Blockchain-timestamped data ensures tamper-proof, audit-ready records.
