Abstract
One of the mechanical property of rocks is destruction specific energy that estimated from the area (integral) under the stress–strain curve in unconfined compression test. The minerals in the rocks are effective on the mechanical properties of the rocks. In this study, the relation between destruction specific energy and mineral shape properties were investigated. The unconfined compressive tests were performed on nine different rock samples and the destruction specific energy values were estimated with calculating the area (integral) under the stress-strain curve for each rock sample. The texture coefficient approach was used for determining of the mineral shape properties and the texture coefficient values were calculated for each rock sample. The results were analyzed with using linear regression analyze method and a strong relation was found between destruction specific energies and the texture coefficients of rocks.

Abstract
Kayaçların mekanik özelliklerinden birisi Spesifik Deformasyon Enerjisi olup tek eksenli basınç dayanımı testinde elde edilen gerilme deformasyon eğrisi altında kalan alandan hesaplanmaktadır. Kayaç içerisindeki minerallerin de kayaçların mekanik özelliklerine etkisi vardır. Bu çalışmada mineral şekil özellikleri ile spesifik deformasyon enerjisi arasındaki ilişki araştırılmıştır. Dokuz farklı kayaç numunesi üzerinde basınç dayanımı testleri yapılmış ve her bir kayaç için gerilme deformasyon eğrileri altında kalan alan hesaplanarak spesifik deformasyon enerjisi değeri bulunmuştur. Kayaçlar içerisindeki mineral özellikleri belirlenirken doku katsayısı yaklaşımı kullanılmış ve her bir kayaç için doku katsayısı değeri belirlenmiştir. Doğrusal regresyon analizi yöntemi kullanılarak elde edilen veriler istatistiksel olarak analiz edilmiş ve spesifik deformasyon enerjisi (SEDef) ile doku katsayısı (TC) arasında güçlü bir ilişki bulunmuştur.
