Estimating material properties is an essential part of any engineering field. In rock mechanics, obtaining an infinite number of samples and/or samples at desired orientations is often not possible. Thus, replica materials have been extensively used to serve in the laboratory as analogues of natural rock. In this note, a framework is established to assess the suitability of a replica material to replicate natural rock for research purposes. The framework involves the evaluation of the mechanical properties in terms of the modulus ratio and the strength ratio. This framework is used to evaluate the adequacy and suitability of a plaster-like material, commercially known as “Flowstone”. The replica material formation process most closely resembles that of sedimentary rocks. From a physical and mechanical perspective, the modulus ratio, strength ratio, Poisson's ratio, and density fall within ranges that define sedimentary rock, indicating that this replica material is a suitable analogue to rock (i.e., ‘rock-like materials' or ‘synthetic rocks').

应用于商业石膏水泥的合成类岩石材料评价示例框架

估计材料特性是任何工程领域的重要组成部分。在岩石力学中,获取无限数量的样本和/或所需方向的样本通常是不可能的。因此,复制材料已被广泛用于实验室,作为天然岩石的类似物。在本说明中,建立了一个框架来评估复制材料复制天然岩石以用于研究目的的适用性。该框架涉及根据模量比和强度比评估机械性能。该框架用于评估石膏类材料(商业上称为“Flowstone”)的充分性和适用性。复制材料的形成过程与沉积岩最相似。从物理力学角度看,模量比、强度比、
