Description
Yuanjian Zhang and colleagues struck layered rock samples in two thousand twenty-five. Real rock masses mix hard and soft layers. A soft interlayer sits between hard sections. Its thickness may change how the mass breaks. The team used a split-bar impact device. Sandstone and granite played soft and hard roles. Computer simulation tracked cracks and damage growth.
Thicker interlayers resisted crack growth more strongly. They also absorbed more energy before failing. Stored elastic energy built up under impact. The interlayer reached its limit first and failed fast. Its failure then drove the whole mass apart. Mining and tunnel engineers gain failure insight.
