fis-1201	Kuidong, Gao; Changlong, Du; Hongxiang, Jiang; Songyong, Liu	A theoretical model for predicting the Peak Cutting Force of conical picks	2013	10	.pdf	application/pdf	4045	150	50	For these reasons, the vertical fracture mechanics model of rock cutting fragment is established based on the maximum tensile criterion and rock cutting theory in this paper firstly; then, the theoretical model for predicting the PCF of conical pick is I http://dx.medra.org/10.3221/IGF-ESIS.27.06&auth=true http://www.gruppofrattura.it G. Kuidong et alii, Frattura ed Integrità Strutturale, 27 (2014) 43-52; DOI: 10.3221/IGF-ESIS.27.06 44 established based on elastic fracture mechanics theory; finally, the reliability and accuracy of PCF model is verified with experimental date.
