Modulus of Elasticity for Grain-Supported Carbonates—Determination and Estimation for Preliminary Engineering Purposes

The determination and estimation of elastic behaviour are essential in engineering practise, especially quarrying, mining, construction, all professions that perform operations dealing with rock materials. Young’s modulus, or modulus elasticity, is the most important property describing deformability material. In this paper, grain-supported carbonates from Croatia described their significant physical mechanical properties determined. analysis collected data was performed R statistical environment. Estimation models based on multiple linear regression tree model were created. methodology development evaluation environment detail. According to more stringent coefficients (RMSECV adjusted R2) used evaluate success estimation, simple found well for preliminary while complex Bagging very well.
