Abstract

In this study, hardness measurements were carried out by applying one-way compression to the high-density polyethylene (HDPE) material at different rates. The amount of deformation was made at room conditions approximately at 23 °C and 50% humidity with 10%, 20%, 30%, 40%, 50%, 60%, 70% and 80% strain ratios. Compression processes were made on 3 mm thick plate samples. The pressing direction was carried out in the direction of thickness. The hardness and stress values of the samples were determined which were subjected to compression processes. In addition, plastic deformation rates for each compression ratio were calculated. The highest hardness value was determined at a 10% compression ratio, and it was observed that the hardness values decreased with increasing compression ratios. In plastic deformation rates, the permanent deformation of 10% and 20% is very slight, and apart from these, a remarkable increase has been observed with increasing deformation rates.

Abstract

Bu çalışmada yüksek yoğunluklu polietilen (HDPE) malzemeye farklı oranlarda tek yönlü basma işlemi uygulanarak sertlik ölçümleri gerçekleştirilmiştir. Şekil değişim miktarları %10, %20, %30, %40, %50, %60, %70 ve %80 oranlarında oda şartlarında yaklaşık 23 °C and %50 nemde gerçekleştirilmiştir. Basma işlemleri plaka şeklinde 3 mm kalınlığında numunelere yapılmıştır. Basma yönü kalınlık doğrultusunda gerçekleştirilmiştir. Basma işlemleri yapılan numunelerin sertlik değerleri ve gerilme değerleri tespit edilmiştir. Ayrıca her bir sıkıştırma oranı için plastik deformasyon oranları hesaplanmıştır. %10 basma oranında en yüksek sertlik değeri tespit edilmiş olup artan basma oranlarında sertlik değerlerinin düştüğü gözlemlenmiştir. Plastik deformasyon oranlarında ise %10 ve %20 oranlarında kalıcı şekil değişimi çok düşük değerlerde olup artan deformasyon oranlarında dikkate değer bir artış görülmüştür.
