  1. 1. Deformability of unidirectional prepreg materials

    Author : Ylva Larberg; Malin Åkermo; Patrik Fernberg; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prepreg; deformability; carbon composite; Vehicle engineering; Farkostteknik;

    Abstract :  To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An automatic tape layer (ATL) can be used to perform the lay-up in an efficient way. READ MORE

  2. 2. Microfluidics Separation and Analysis of Biological Particles

    Author : Jason Beech; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Point-of-care; Lab-on-a-chip; Microfluidics; Separation science; Deterministic Lateral Displacement; morphology; deformability; Fysicumarkivet A:2011:Beech;

    Abstract : In the last decade, powerful communication and information technology in the form of the mobile phone has been put into the hands of more than 50% of the global population. In stark contrast, a lack of access to medical diagnostic technology with which to diagnose both communicable and non-communicable diseases will mean that many of these people will die of easily treatable conditions.

  4. 4. Strength and deformability of fractured rocks

    Author : Majid Noorian-Bidgoli; Lanru Jing; John A. Hudson; KTH; []
    Keywords : Fractured crystalline rocks; Numerical experiments; Discrete element methods DEM ; Discrete fracture network DFN ; Representative elementary volume REV ; Coupled hydro-mechanical processes; Anisotropy; Effective stress; Failure criteria; Stochastic realizations; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : This thesis presents a systematic numerical modeling framework to simulate the stress-deformation and coupled stress-deformation-flow processes by performing uniaxial and biaxial compressive tests on fractured rock models with considering the effects of different loading conditions, different loading directions (anisotropy), and coupled hydro-mechanical processes for evaluating strength and deformability behavior of fractured rocks. By using code UDEC of discrete element method (DEM), a series of numerical experiments were conducted on discrete fracture network models (DFN) at an established representative elementary volume (REV), based on realistic geometrical and mechanical data of fracture systems from field mapping at Sellafield, UK.
