Experimental Study on the Fracture Evolution Processof Rock-like Specimens Containing a Closed RoughJoint Based on 3D-Printing Technology

<div>Evolution process of strain fields of specimens containing closed 3D-printing rough joints with different joint inclinations under uniaxial compression (<i>l</i> = 40.0 mm). (a) Specimen T30-2# (<i>α</i> = 30°), (b) specimen T45-2# (<i>α</i> = 45°), (c) specimen T60-2# (<i>α</i> = 60°), and (d) specimen T90-1# (<i>α</i> = 90°).</div>
