2021年4月15日 · Here, the effect of stacking sequence on the R-curve and traction-separation relation in unidirectional and multidirectional CFRP DCB laminates with designed generic +θ°/−θ° and 0°/θ° interfaces were systematically investigated, and interpreted combining with the fractographical analysis of failed fracture surface.

Junan Tao's 4 research works with 115 citations, including: A semi-analytical method for determining mode-II fracture toughness and bridging law of composite laminates

2022年5月15日 · Researchers have proposed different approaches to obtain the bridging traction-separation relation of mode I delamination. One way is to measure the crack opening profile near the crack tip.

在这项工作中，基于Castigliano定理和点摩擦理论，建立了模式II断裂韧性和桥接律的半解析方法。 对 T800 碳/环氧树脂层压板进行 ENF 测试并获得断裂韧性。 其他不同材料制成的层压板的公共数据也用于验证。 结果表明，半解析法计算的断裂韧性与实验结果吻合较好，验证了所提出的断裂韧性测定方法的准确性。 此外，还计算了预裂纹尖端的相对剪切位移，并建立了其与断裂韧性的关系， J- 积分理论。 将确定的桥接律集成到粘合区模型中，用于分层增长建模。 数值和实验载 …

2020年7月1日 · Here, a simple procedure is proposed for the determination of mode I bridging law. The crack opening displacement (COD) at the initial pre-crack tip is obtained by a numerical method based on the experimental R -curve from standard DCB tests.
