SUMMARY The aim of this paper was to present a topology optimization methodology for obtaining robust designs insensitive small uncertainties in the geometry. variations are modeled using stochastic field. model can represent spatially varying geometry imperfections devices produced by etching techniques. Because under‐etching or over‐etching parts structure may become thinner thicker than reference design supplied manufacturer. assumed be and their influence on system response is evaluated...
Abstract The capability to analyze structures under static and dynamic loads is an essential skill for structural engineers. Structural analysis therefore a key component in civil architectural engineering education, where analytical methods are traditionally complemented by the use of (commercial) software packages. latter often closed source, which may obscure links underlying matrix or finite element formulation. To stimulate active, cooperative, solution‐oriented learning, we developed...
Abstract. The aim of this article is to introduce a new topology optimisation formulation for optimal robust design Micro Electro Mechanical Systems. Mesh independence in most often ensured by using filtering techniques, which result transition grey regions difficult interpret practical realisations. This problem has been alleviated recently projection but these destroy the mesh introduced filters and single node connected hinges. Such features are undesirable as they not with respect...
This paper presents optimization methods to design frame structures from a stock of existing elements. These are relevant when reusing structural elements over multiple service lives. Reuse has the potential reduce environmental impact building because it avoids sourcing new material, reduces waste and requires little energy. When elements, cross-section length availability have major influence on design. In previous own work, truss was formulated as mixed-integer linear programming (MILP)...
This paper presents a novel technique for the determination of material damping ratio in shallow soil layers. It is based on spectral analysis surface waves (SASW) test. The an alternative to existing methods, where determined from spatial decay Rayleigh wave. These methods rely knowledge geometric damping, and may lead incorrect results if calculated inaccurate shear wave velocity profile. also when higher modes contribute wavefield soil. In proposed technique, transformed...
SUMMARY This paper presents a perfectly matched layer (PML) technique for the numerical simulation of three‐dimensional linear elastodynamic problems, where geometry is invariant in longitudinal direction. Examples include transportation infrastructure, dams, lifelines, and alluvial valleys. For longitudinally geometries, computationally efficient two‐and‐a‐half‐dimensional (2.5D) approach can be applied, Fourier transform from coordinate to wavenumber domain allows representation radiated...
