Finite Element Simulations of Polycrystals
Computational Material Modeling, 1994Abstract The finite element method provides a flexible and powerful framework in which polycrystal plasticity theory may be implemented. The relative sizes of crystals and elements may span orders of magnitude: elements may be small or large compared to crystals. When they are large the finite element discretization is of a continuum,

Die Belastungsrandbedingung bei der numerischen Berechnung der durchgefuhrten Kopfaufprallversuche wird uber ein detailliertes FE–Modell des Kopfimpaktors aufgebracht. Um eine moglichst realitatsnahe Abbildung des mechanischen Verhaltens und somit eine reprasentative Prognose der fur den HIC–Wert masgebenden Beschleunigungskomponenten zu gewahrleisten,

Finite Element Simulation of Nanoindentation Process
2013Recently, nanoindentation technique is gaining importance in determination of the mechanical parameters of thin films and coatings. Most commonly, the instrumented indentation data are used to obtain two material characteristics of bulk materials: indentation modulus and indentation hardness.

Finite element modeling in surgery simulation
Proceedings of the IEEE, 1998Modeling the deformation of human organs for surgery simulation systems has turned out to be quite a challenge. Not only is very little known about the physical properties of general human tissue but in addition, most conventional modeling techniques are not applicable because of the timing requirements of simulation systems.

Finite element simulation of microindentation
Russian Metallurgy (Metally), 2017Finite element models are created to describe the testing of a material by a Berkovich indenter. The results of calculations by these models are compared to experimental data on indentation of the same material (grade 10 steel). The experimental and calculated data agree well with each other.

Elasto-Plastic Finite Element Simulations
2014The continuum mechanics basics for plasticity, i.e. the yield condition, the flow rule, the hardening law, and the elasto-plastic modulus, for the one-dimensional rod will be used to describe the elasto-plastic behavior for monotonic and cyclic loading.

Essentials for Finite Element Simulation
2014Finite Element (FE) simulation solves the mathematical model of the physical problem. The following sections discuss the essential elements for the FE simulation process with respect to an illustrative problem in the assessment of solder joint reliability.

Higher-order finite elements for embedded simulation
ACM Transactions on Graphics, 2020As demands for high-fidelity physics-based animations increase, the need for accurate methods for simulating deformable solids grows. While higherorder finite elements are commonplace in engineering due to their superior approximation properties for many problems, they have gained little traction in the computer graphics community.

Finite element simulation to improve the sensitivity of a MIT
2015 IEEE 12th International Multi-Conference on Systems, Signals & Devices (SSD15), 2015In the field of magnetic inductance tomography, signal processing is a real challenge. This is due to the divergent nature of magnetic fields. The sensitivity, i.e. the change in the receiving signal by means of an electrically conductive sample in a measuring volume depends strongly on the positioning of the sample.
