In addition, according to the effect of the single joint angle on the strength of the single-crack rock specimen, when fi satisfies the following (5), sliding failure along the joint plane direction occurs in the single-crack rock, and the corresponding strength is the lowest [31].
Study on Failure Process and Permeation Evolution of Single-Cracked Rock
performed the conventional triaxial compression tests on the marble specimens containing natural joints, and the effects of joint angle (between the joint plane and major principal stress) varying from 29.3[degrees] to 56.0[degrees] on the strength and failure model were studied [4].

In this model, after the joint plane is defined, a smooth joint (SJ) is assigned to the contacts between the particles.

The smooth joint can be envisioned as a set of elastic springs uniformly distributed over a circular cross-section, centered at the contact point and oriented parallel with the joint plane. Once the SJ model is created, preexisting parallel bonds would be deleted and replaced with SJ model.

In accordance with the methodology of the quantitative description of discontinuities in rock mass (ISRM, 1983), the interval between joints of each system, persistence of joint, roughness of joint plane, joint separation, minerals filling and the amount of the potential inflow intensity of water were monitored.

IR preheating of the joint plane almost eliminates particulates, and active braking of the vibration head increases weld strength significantly, claims Branson.
Plastics welding: laser & infrared systems expand capabilities: servo drives, improved controls, and more rigid construction characterize a number of new welding systems. There are also new capabilities in the up-and-coming technologies of laser and IR transmission welding
After the fracture propagates along the joint and overlaps the joint plane, it propagates along these overlapped joints.
