Introduction The fracture and failure of brittle disordered solid materials under external forces, for example, the fracturing of concrete [1], cellular glass [2], and in volcanic and seismicity activity [3], is a longstanding intriguing problem that has plagued numerous researchers in both engineering science and solid physics for several decades.
There are, however, a couple of problems associated 2-D numerical models which limit its range of application in practical rock engineering problems.

Adhesive joints are essential in modern engineering, offering lightweight, durable and efficient solutions for bonding in industries such as aerospace, automotive, and renewable energy.
Introduction Adhesive bonding has become an essential technology in modern engineering for joining materials in a variety of industries, including automotive, aerospace, marine, and civil engineering.
Understanding these interdependencies is essential for enhancing the durability and reliability of adhesive joints in demanding engineering applications.
Accurate life prediction allows engineers to design joints that meet performance requirements while avoiding premature failure.
They allow engineers to estimate the probability of failure and design joints with appropriate safety factors [8].
