Crack patterns of 100-nm thick silicon oxide coatings on poly(ethylene terephthalate), polypropylene and polyamide films are analyzed under equibiaxial stress loading. The loading is achieved by means of a bulging cell mounted under an optical microscope w ...
In this paper, we use the established cohesive element method to investigate the probabilistic failure of a model ceramic system under dynamic tensile loading. Monte-Carlo simulations are performed to calculate the fracture strength of a monolithic silicon ...
The one-dimensional fragmentation of a dynamically expanding ring (Mott's problem) is studied numerically to obtain the fragment signatures under different strain rates. An empirical formula is proposed to calculate an average fragment size. Rayleigh distr ...
Isoelectric focusing in a polyacrylamide pH gradient gel is used to analyze the size distribution of gold nanoparticles synthesized by a chemical route with mercaptosuccinic acid as a ligand. The isoelectric point of the nanoparticles is shown to be size d ...
In this paper, two brittle fracture problems are numerically simulated: the failure of a ceramic ring under centrifugal loading and crack branching in a PMMA strip. A three-dimensional finite element package in which cohesive elements are dynamically inser ...
Three-dimensional numerical simulations are performed to investigate the dynamic tensile properties of ceramics, using explicit dynamic FEM and cohesive element techniques. A micro-cracking model considering the stochastic distribution of internal defects ...
A new aerosol model, the Model of Aerosol Dynamics, Reaction, Ionization, and Dissolution (MADRID) has been developed to simulate atmospheric particulate matter (PM). MADRID and the Carnegie-Mellon University (CMU) bulk aqueous-phase chemistry have been in ...
This paper discusses the integration of material flux analysis and agent analysis as the basis for a transition towards improved regional wood management in Appenzell Ausserrhoden (AR), a small Swiss canton located in the Pre-Alps of Switzerland. We presen ...
This paper presents a validation study on statistical non-supervised brain tissue classification techniques in MR images. Several image models assuming different hypotheses regarding the intensity distribution model, the spatial model and the number of cla ...
The 10CrMoNbV Manet II cast has been selected as the reference ferritic-martensitic steel in the framework of the European Fusion Technology Programme. Charpy impact tests have been carried out in the ductile to brittle transition temperature range of this ...
