Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...

From the 9th to the 11th November 2008, the ChemistryInformation-Computers (CIC) division of the German Chemical Society (GDCh) has invited the chemoinformatics and modeling community to Goslar, Germany to participate in the 4th German Conference on Chemoinformatics (GCC). Almost 200 participants from 14 countries accepted the invitation making the event again one of the largest chemoinformatic...

Variations in laser irradiance and local temperatures in laser sintering cause variations in porosity and material microstructure, which can affect mechanical properties of a part. From the design perspective, it is important to model microstructures, mechanical properties, and their relationships so that parts can be analyzed and designed taking into account their asmanufactured condition. In ...

Molecular/atomic-level computer modeling of laser–materials interactions is playing an increasingly important role in the investigation of complex and highly nonequilibrium processes involved in short-pulse laser processing and surface modification. This chapter provides an overview of recent progress in the development of computational methods for simulation of laser interactions with organic ...

This paper presents the numerical modeling of a plate structure containing bonded piezoelectric material. Hamilton’s principle is employed to derive the finite element equations using the mechanical energy of the structure and the electrical energy of the piezoelectric material. Then, a numerical model is developed based on Kirchhoff’s plate theory. A computational program is implemented for an...

Plasma/material interactions is a critical scientific issue for fusion power, with major potential limitations on plasma core and edge operating parameters. Gaining understanding and predictive capability in this area will require simultaneously addressing complex and diverse physics occurring over a wide range of lengths (angstroms to meters) and times (femtoseconds to days). This requires fur...

After decades of research on digital representations of material and object appearance, computer graphics has more recently turned to the problem of creating physical artifacts with controllable appearance characteristics. While this work has mostly progressed in two parallel streams – display technologies as well as novel fabrication processes – we believe there is a large overlap and the pote...

1 The working material is incomplete and may contain errors. Any suggestions are greatly appreciated. Notation In this book we will make the following notational conventions: a constant b constant C unary relation symbol denoting a concept C set of concept formulas D non-empty domain of an interpretaion E set of equations Es expression containing an occurrence of the term s Es/t expression wher...

The general and practical inversion of diffraction data-producing a computer model correctly representing the material explored-is an important unsolved problem for disordered materials. Such modeling should proceed by using our full knowledge base, both from experiment and theory. In this paper, we describe a robust method to jointly exploit the power of ab initio atomistic simulation along wi...

Introduction What impact can mathematical modeling have in the production industry? Our partnership with Almatis B.V., a special purpose cement manufacturer, resulted in the complete elimination of unscheduled plant shut-downs. Almatis now reports a much more stable manufacturing process and hence a very significant productivity increase. The key to our success resides in the deployment of adva...
