Materials research represents a significant part of the European and world effort on fusion research. Detailed knowledge of materials properties is needed in the design by analysis of power plant and experimental machine components, and in testing to design fusion materials with specific properties, a process that involves collection and examination of a large number of data. In response, a Eur...

Research on material perception has received an increasing amount of attention recently. Clearly, both the visual and the haptic sense play important roles in the perception of materials, yet it is still unclear how both senses compare in material perception tasks. Here, we set out to investigate the degree of correspondence between the visual and the haptic representations of different materia...

The present paper introduces a numerical simulation aided, experimental method for the measurement of Young's modulus of the trabecular substance in the human mandible. Compression tests were performed on fresh cadaveric samples containing trabecular bone covered with cortical layer, thus avoiding the destruction caused by the sterilization, preservation, and storage and the underestimation of ...

The paper presents a combined experimental and theoretical study to determine the actual dynamic Young’s modulus (Edynamic) for the mechanical structure of a silicon microaccelerometer. The resonance (natural) frequencies of the suspension arms of accelerometer were measured using MSA-500 Micro System Analyzer and, then, introduced in analytical expressions in order to find Edynamic. The obtain...

In this contribution a brief overview of the development of an orthotropic material model for the simulation of spruce wood under simultaneous plane and transverse shear stresses is given. The model considers an initially linear elastic domain as well as plasticity behaviour including hardening and softening mechanisms at higher states of stress and strain, respectively. The newest feature of t...

Batisite was reported to be a nonlinear optical material showing second harmonic generation. Using dielectric spectroscopy and polarization measurements, we provide a thorough investigation of the dielectric and charge-transport properties of this material. Batisite shows the typical characteristics of a linear lossy dielectric. No evidence for ferro- or antiferroelectric polarization is found....

This presentation describes the contribution of the group at KUN to Work-packages 2 and 3 in the following directions: (1) study of the properties and the behavior of variable versus fixed preconditioners, based on the so-called separate displacement component (SDC) formulation of the linear elasticity problem; (2) solution of problems with nearly incompressible material properties, based on a ...
