The reliability and longevity of the guiding shoe are crucial for the proper functioning of coal mining machines. The heavy wear of the sliding surface under thermal stress coupling is the primary factor influencing the service life of the guiding shoe.
The detailed flowchart is presented as below. 𝑘𝑛=4𝐸𝑐𝑅,𝑘𝑠=𝑘𝑟𝑘𝑛kn=4EcR,ks=krkn (9) 𝜑𝑛𝑡=4𝜎𝑐𝑅2,𝜑𝑠=4𝜏𝑐𝑅2φnt=4σcR2,φs=4τcR2 (10) Given the large values for strength parameters (𝜑𝑛𝑡,𝜑𝑠,𝜑𝑛𝑐𝑟,...
High-Performance Concrete (HPC) and Ultra-High-Performance Concrete (UHPC) have many applications in civil engineering industries. These two types of concrete have as many similarities as they have differences with each other, such as the mix design and additive powders like silica fume, metakaolin...
The present work is part of the second line of research undertaken by the WASP (the World’s Advanced Saving Project) with the collaboration of the Department of Civil, Environmental and Materials Engineering of the University of Bologna (Italy), which deals with the mechanical characterization of...
