岩石力学行为的简单模型中出现的复杂性

Emerging complexity in a simple model of the mechanical behaviour of rocks

David Amitrano

摘要:

我们提出了一个力学模型的岩石行为的基础上渐进损伤的基本尺度和弹性相互作用。它使我们能够模拟几个实验观察:从脆性到韧性的力学行为,分形结构的损害,幂律分布的损害雪崩。这些宏观性质不是在元素尺度上结合的,而是元素之间相互作用的结果。这种新出现的复杂性使我们能够考虑应变岩石过程作为一个复杂系统的特点是非线性动力学。

英文摘要:

We propose a mechanical model for the behaviour of rocks based on progressive damage at the elementary scale and elastic interaction. It allows us to simulate several experimental observations: mechanical behaviour ranging from brittle to ductile, fractal structure of the damage, powerlaw distribution of the damage avalanches. These macroscopic properties are not incorporated at the elementary scale, but are the results of the interaction between elements. This emerging complexity permits us to consider the strain rock process as a complex system characterized by non-linear dynamics.
