Finite Element-Based Model for Crack Propagation in Polycrystalline Materials∗
In this paper, we use an extended form of the finite element method to study failure in polycrystalline microstructures. Quasi-static crack propagation is conducted using the extended finite element method (X-FEM) and microstructures are simulated using a kinetic Monte Carlo Potts algorithm. In the X-FEM, the framework of partition of unity is used to enrich the classical finite element approxi...
متن کاملPerturbation-based Finite Element Analyses of Transmission Line Galloping
Efficient perturbation schemes are developed to compute the large amplitude, low frequency, galloping vibrations of a multi-span, overhead transmission line. Systematic procedures are formulated to assess the stability of a conductor’s wind and ice loaded static profile by employing a multiple-degree-of-freedom finite element model. The use of the computationally most demanding part of the fini...
متن کاملFinite Element Stochastic Analysis
Numerical models can be valuable tools in the prediction of seepage. The results can often be misleading if proper variational analysis is not performed. Measurement of the soil-water characteristic curve (SWCC) or saturated and unsaturated hydraulic conductivity information is often neglected or minimized. The modeller is therefore forced to develop a seepage model based on estimated soil prop...
متن کاملFinite-element-simulations of polycrystalline shape memory alloys
Shape memory alloys (SMA) are widely employed as sensors and actuators. The need for precise control requires reliable modeling techniques involving, e.g., prescribed stresses and temperatures. These parameters are always inherently coupled in SMA. Various models are in use to characterize the non-linear hysteretic behavior of SMA; among them some that do not provide a means to incorporate true...
متن کاملFree Vibration Analysis of Nanoplates Made of Functionally Graded Materials Based On Nonlocal Elasticity Theory Using Finite Element Method
In this paper, an analysis of free vibration in functionally graded nanoplate is presented. Third-order shear deformation plate theory is used to reach more accuracy in results. Small-scale effects are investigated using Eringen`s nonlocal theory. The governing equations of motion are obtained by Hamilton`s principle. It is assumed that the properties of nanoplates vary through their thicknesse...
