论文摘要
在先前的工作中，我们考虑了颗粒的二维晶格，并通过基于粒子本身的空间位置使用相互作用定律来计算其时间演变。该模型根据标准的Cauchy模型和第二梯度理论重现了可变形物体的行为。这种成功使我们在更复杂的情况下使用了这种方法。这项工作旨在作为前一个能量方面的自然演变，与圣地纳特原理保持一致，我们开始管理一个可以适应不同物理现象的更通用工具，支持复杂的效果，例如横向收缩，各向异性或弹性性。
In a previous work we considered a two-dimensional lattice of particles and calculated its time evolution by using an interaction law based on the spatial position of the particles themselves. The model reproduced the behaviour of deformable bodies both according to the standard Cauchy model and second gradient theory; this success led us to use this method in more complex cases. This work is intended as the natural evolution of the previous one in which we shall consider both energy aspects, coherence with the principle of Saint Venant and we start to manage a more general tool that can be adapted to different physical phenomena, supporting complex effects like lateral contraction, anisotropy or elastoplasticity.
