Abstract

Malzemelerin yorulma testleri, tüm süreç dikkate alındığında diğer birçok mekanik teste göre daha uzun süre gerektirmektedir. Test süresini etkileyen en önemli faktörlerden biri yorulma test frekansıdır. Bu çalışmada Eİ tekniğiyle üretilen PLA parçalara farklı test frekanslarında yorulma testi uygulanmış ve test frekansının etkileri araştırılmıştır. Yorulma testlerinde dört farklı gerilme seviyesi uygulanmış ve testler 2 Hz, 4 Hz, 6 Hz ve 8 Hz olmak üzere dört farklı frekansta gerçekleştirilmiştir. Uygulanan gerilme seviyelerine göre değişen test frekanslarında farklı yorulma ömürleri bulunmuştur. 1. Gerilme seviyesinde artan test frekansıyla bulunan yorulma ömründe yaklaşık %44 azalma görülmüştür. 3. Gerilme seviyesi ve sonrası yorulma ömrü artan trend göstermiştir. 4. Gerilme seviyesinde test frekansı 2 Hz’den 8 Hz’e değiştirildiğinde yorulma ömrü %45 artmıştır. Genel olarak, belirli yorulma ömür değerinden sonra artan test frekansının yorulma ömrünü arttırma eğiliminde olduğu görülmüştür.

Abstract

Fatigue tests of materials require longer time than most other mechanical tests when the enitre process is considered. One of the most critical factors affecting the test time is the test frequency. In this study, fatigue tests at different test frequencies were applied to the PLA parts produced by the additive manufacturing (AM) technique, and the effects of test frequency were investigated. In the fatigue tests, four different stress levels were applied, and the tests were carried out at four different frequencies: 2 Hz, 4 Hz, 6 Hz, and 8 Hz. The fatigue life of the samples changed according to the applied stress levels at varying test frequencies. There was an approximately 44% decrease in the fatigue life found with increasing test frequency at the 1st stress level Fatigue life showed an increasing trend at and after the 3rd stress level. At the 4th stress level, fatigue life increased by 45% when the test frequency was changed from 2 Hz to 8 Hz. In general, after a specific fatigue life, it was observed that increasing test frequency tended to increase the fatigue life.
