Abstract

In this study, a unique fatigue testing machine, which characterizes the flexural fatigue behavior of fiber-reinforced composite plates, wooden plates, plastic-based plates and light metal plates, has been developed. Fixed-end type flexural fatigue test machine, which can be controlled by developed special computer software, uses displacement control method for fatigue tests. Fatigue tests are long-running mechanical tests. The developed fatigue test machine can save time and energy under favor of the ability to test 10 samples simultaneously. Fatigue tests can be performed under different displacement rates (R) and 0,1-1Hz frequency with simple data entries via the software interface. All parameters such as test time, test frequency, bending force, loss of stiffness, load repetition for each sample can be monitored and controlled both in software interface and on internet. If any of the specimens are damaged, a warning message is sent to the investigator's e-mail along with the relevant test data. It has been observed that the results, which were obtained from the bending tests performing for performance and calibration, are consistent with those in the literature.

Özet

Bu çalışmada, fiber takviyeli kompozit levhalar, ahşap levhalar, plastik esaslı levhalar ve hafif metalik levhaların eğilmeli yorulma davranışlarını karakterize eden özgün bir yorulma test makinesi geliştirilmiştir. Geliştirilen özel bilgisayar yazılımı ile kontrol edilebilen ankastre-tip eğilmeli test makinesi, yorulma testi için deplasman kontrol metodunu kullanmaktadır. Yorulma testleri uzun süren mekanik testlerdendir. Geliştirilen test makinesi aynı anda 10 numuneyi test edebilme özelliği sayesinde zamandan ve enerjiden tasarruf edilebilmektedir. Yazılım ara yüzü üzerinden yapılacak basit veri girişleri ile farklı sehim oranları (R) ve 0.1-10 Hz frekans altında yorulma testleri yapılabilmektedir. Her bir numune için test zamanı, test frekansı, eğme kuvveti, rijitlik kaybı, yük tekrar sayısı gibi parametreler hem yazılım ara yüzünden hem de internet üzerinden izlenebilmektedir ve müdahale edilebilmektedir. Numunelerinden herhangi biri hasara uğradığında araştırmacının e-postasına uyarı mesajı ve ilgili test verilerini gönderebilmektedir. Performans ve kalibrasyon için yapılan eğilme testlerinden elde edilen sonuçların, literatürdeki benzerleri ile uyumlu olduğu gözlemlenmiştir.
