In this article, we introduce a new method for the accurate and fast computation of singular integrals over cuboids in three-dimensional space. Using a straightforward geometric parametrisation of the domain of integration, we interpret the integral as a smooth function on a high-dimensional parameter space. A standard interpolation scheme then leads to a(More)
In a previous part I, we introduced a method for the evaluation of singular integrals arising in the discretization of integral equations based on the repeated subdivision of domains. The integrals defined on these subdomains are classified such that a class of integrals can be expressed as a sum of regular integrals and representatives of other classes. A(More)
In this paper, building blocks of a MEMS tensile testing platform are presented. The building blocks include a thermo-mechanical MEMS actuator, driven by an aluminum thin-film heater on a thermal oxide for electrical insulation, a capacitative displacement sensor and a piezoresistive force sensor, capable of measuring forces on a nano-newton scale. It is(More)
In this paper we present results of our recent efforts to understand the mechanical interface behaviour of single-walled carbon nanotubes (CNTs) embedded in metal matrices. We conducted experimental pull-out tests of CNTs embedded in Pd or Au and found maximum forces in the range 10-102 nN. These values are in good agreement with forces obtained from(More)
For the development of lifetime models in a physics-of-failure approach for microelectronic devices and functional elements on the submicron or even nanoscopic scale, the exact knowledge of the materials in use and their failure behavior is imperative. A piezoresistive MEMS force sensor, which can be integrated in MEMS sized tensile and fatigue test stages,(More)
