Abstract Inspired by the fundamental principle that inherent defects, such as primary pores and fractures in natural rocks, significantly influence their mechanical properties, this paper introduces the Mechanic-Controlled Sampling via Structure-Driven Design (MSSD) method for fabricating transparent rock-like samples with controllable mechanical characteristics. Utilizing this method, we fabricated intact and pre-fissured transparent rock-like samples with varying porosities (0%, 3%, 6%, 10%, 20%, and 30%). We established quantitative relationships between porosity and key mechanical parameters, including uniaxial compressive strength, elastic modulus, tensile strength, brittleness, cohesion, and internal friction angle. The influence mechanism of pores on crack propagation was elucidated through Franc3D simulations. Experimental results from intact samples demonstrate that the failure modes are highly consistent with those observed in natural rocks, allowing for clear observation and capture of the crack propagation process. As porosity increases, the various mechanical parameters of intact samples exhibit a linear decreasing trend, transitioning from hard rock-like material to soft rock-like material. Experimental results from pre-fissured samples indicate that increasing porosity leads to heightened surface roughness of wing cracks in single-fissure samples. In double-fissure samples, the rock bridge coalescence mode shifts from global to local coalescence, with the stress intensity factor KIII at the crack tip gradually decreasing, while the fracture mode in the rock bridge area transitions from tensile to shear type. Moreover, an increase in porosity correlates with a reduction in the number of petal-shaped cracks observed in all pre-fissured samples.
