A combined application of two soft computing algorithms for weathering degree quantification of andesitic rocks
Köken, Ekin; Kadakci Koca, Tümay (ELSEVIER, 2022)Understanding the variations in physical and mechanical behavior of rock materials due to progressive weathering is vital to carry on time and cost-effective engineering projects. Up to date, soft computing algorithms ... -
A comparative study to estimate the mode I fracture toughness of rocks using several soft computing techniques
Köken, Ekin; Kadakçı Koca, Tümay (Mersin Üniversitesi, 2023)Fracture toughness is an important phenomenon to reveal the actual strength of fractured rock materials. It is, therefore, crucial to use the fracture toughness models principally for simulating the performance of fractured ... -
Estimation of cohesion for intact rock materials using regression and soft computing analyses
Köken, Ekin; Strzałkowski P.; Kazmierczak U. (Institute of Physics, 2024)Shear strength parameters such as cohesion (c) and internal friction angle (.) are among the most critical rock properties used in the geotechnical design of most engineering projects. However, the determination of these ... -
An experimental investigation on rock crushability using jaw and cone crushers
Köken, Ekin; Bilen, M.; Özarslan, A.; Barış, K. (Baski, 2019)This study covers the investigation of rock crushability using laboratory-scale cone and jaw crushers for five types of hardrocks. For this purpose, physico‒mechanical properties of the investigated rocks are determined. ... -
Guidelines for Natural Stone Products in Connection with European Standards
Strzalkowski, Pawel; Köken, Ekin; Sousa, Luís (MDPI, 2023)The selection of ornamental stones for specific applications requires technical guidance since it should be based on the durability, service life, and aesthetic value of the stones. In most cases, these fundamentals provide ... -
