Bu çalışma, farklı boyutlarda CuTi (B11) kristal nanotellerinin [001] yönündeki esneklik-kırılma mekanizmasını ve deformasyonunu gözlemek için ayrıntılı bir analiz sunmaktadır. Germe oranı ve boyut gibi değişkenlerin nanotelin mekanik özellikleri üzerine etkileri etkileşmelerin gömülü atom potansiyeli ile tanımlandığı moleküler dinamik benzetimleri ile incelenmiştir. Uygulanan dış değişkenlerin CuTi nanotellerinin elastik ve plastik deformasyonları üzerindeki etkileri iki temel başlık altında özetlenmiştir. Nanotelin elastik tepkisinin yüksek germe oranı ve küçük boyut ile arttığı gözlenmiştir. Elastisite Modülünün germe oranı ile de karakterize edilebilmesine rağmen nanotel boyutu istenen dayanıklılık mekanizmasını belirlemede daha etkin role sahiptir. Diğer yandan, düşük germe oranı ve küçük boyutun CuTi nanotellerin kırılma dayanımını ve esnekliğini azalttığı izlenmiştir.
