This book was released on 2017-02-10 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current paper establishes an axisymmetric model for an inductive heating process. Therein, the fully coupled MAXWELL equations, assuming a temperature dependent permeability, are combined with the non-linear heat conduction equation to yield a monolithic solution strategy. The latter is based on a consistent linearization together with a higher order finite element discretization using GALERKIN'S method in space. For the temporal discretization, the generalized Newmark-? methods, higher order RUNGE-KUTTA methods, and discontinuous and continuous GALERKIN methods are used. Furthermore, the residual error is introduced to open an alternative way to obtain a numerically efficient estimation of the time integration accuracy. Simulation results of the electric, magnetic and thermal fields are provided, together with parameter studies concerning spatial discretization, frequency dependence and penetration depth of the heating zone. Another topic analyzed is the residual error and its estimation quality regarding polynomial degree and time step size. A further aspect of this work is the investigation of the thermal fluid-structure interaction with respect to functionally graded materials. Different coupling strategies for the acceleration of the fixed-point iteration in each time step is in the foreground. Relaxation methods as well as extrapolation methods make it possible to significantly reduce the number of fixed point iterations. At the same time, an adaptive strategy with higher order RUNGE-KUTTA methods can provide a further advantage in combination with acceleration methods.

This book was released on 2020-01-20 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present thesis investigates the usage of higher order accurate time integrators together with appropriate error estimators for small and finite dynamic (visco)plasticity. Therefore, a general (visco)plastic problem is defined which serves as a basis to create closed-form solution strategies. A classical access towards small and finite (visco)plasticity is integrated into this concept. This approach is based on the idea, that the balance of linear momentum is formulated in a weak sense and the material laws are included indirectly. Thus, separate time discretizations are implemented and an appropriate coupling between them is necessary. Limitations for the usage of time integrators are the consequence. In contrast, an alternative multifield formulation is derived, adapting the principle of Jourdain. The idea is to assume that the balance of energy - taking into account a pseudopotential representing dissipative effects – resembles a rate-type functional, whose stationarity condition leads to the equations describing small or finite dynamic (visco)plasticity. Accordingly, the material laws and the balance of linear momentum can be solved on the same level and only one single time discretization has to be performed. A greater freedom in the choice of time integrators is obtained and the application of higher order accurate schemes - such as Newmark’s method, fully implicit as well as diagonally implicit Runge-Kutta schemes, and continuous as well as discontinuous Galerkin methods - is facilitated. An analysis and a comparison of the classical and the multifield formulation is accomplished by means of distinct examples. In this context, a dynamic benchmark problem is developed, which allows to focus on the effect of different time integrators. For this investigation, a variety of time discretization error estimators are formulated, evaluated, and compared.

This book was released on 2024-08-29 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the evolving market of product design, the optimization of surface patterns is a crucial factor in determining the functionality of future products. However, despite numerous surface designs introduced in recent years, the field remains significantly underdeveloped. The absence of systematic and well-defined methodologies for generating deterministic topologies has turned the design of surfaces into more of an art than a precise science. This deficiency is further exacerbated by a dominant design culture that attempts to tame nature rather than establish harmonious coexistence within the Man Engineered Systems Domain (MESD). The challenge lies in the lack of a holistic surface design methodology that can merge function, form, and topography to produce optimized constructs capable of efficient operation within an envelope of constraints. Bio-Locomotion Interfaces and Biologization Potential in 4-D Printing is a comprehensive solution to the challenges faced in biomimetic surface design. This groundbreaking book recognizes the underdeveloped state of the field and proposes a trans-disciplinary approach that seamlessly integrates engineering, physics, and biology. It addresses the need for a new surface design methodology, emphasizing the importance of generating bio-inspired functional surfaces in MESD. Unlike existing approaches that rely on mere bio-mimicry, this book delves into the core of design generation, emphasizing the implementation of design rules rather than the replication of natural constructions. It is the ultimate guide for scholars seeking to bridge the gap between biology and engineering and acquire the methodologies needed to deduce design rules and construct deterministic surfaces inspired by bio-analogues.
