有限点集方法是流体力学和连续介质力学中数值求解偏微分方程组的一种无网格方法。区域的几何形状由携带所有必要信息并随材料速度移动的数值点云表示。有限差分法是一种广义有限差分法,因为所考虑问题的强解是由微分算子的直接逼近确定的。土力学中三轴试验的最新应用之一是用因斯布鲁克大学岩土与隧道工程系发展的正压材料定律来模拟土力学中的三轴试验。在土力学中,发展适用于颗粒介质的材料定律对于研究颗粒介质的力学行为以及开发适用于分类和模拟土壤的试验方法具有重要意义。
The Finite Pointset Method (FPM) is a meshfree approach to numerically solve PDEs in fluid dynamics and continuum mechanics. The geometry of the domain is represented by a cloud of numerical points carrying all the necessary information and moving with the material velocity. FPM is a generalized finite difference method as the strong solution of the considered problem is determined by direct approximation of the differential operators. One of the recent applications of FPM is the simulation of triaxial tests in soil mechanics with the material law of barodesy developed by the Division of Geotechnical and Tunnel Engineering at the University of Innsbruck. In soil mechanics the development of appropriate material laws for granular media is important for the research on their mechanical behavior and the development of suitable test procedures to classify and simulate soils.
