2. 1. On computational homogenization of gradient crystal inelasticity

   Author : Kristoffer Carlsson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational homogenization; gradient theory; multiscale modeling; crystal plasticity;

   Abstract : Crystal inelasticity is the main modeling technique employed to study the mechanical behavior of polycrystalline metallic materials. This class of models has the capability to represent micromechanical phenomena such as plastic slip, grain boundary interactions, and dislocation pile-up. READ MORE

4. 2. Permeability of non-crimp fabrics : a computational fluid dynamics approach

   Author : Markus Nordlund; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : In the present market for manufacturing of high performance structural parts for various applications such as aerospace, transportation, infrastructure, marine, sports and recreation, low weight, high performance composites are preferable. Non-Crimp Fabrics (NCFs) are often used for such applications due to its high mechanical properties and often cost effective production. READ MORE

6. 4. Droplet Breakup in Automotive Spray Painting

   Author : Björn O Andersson; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomization; spray painting; computational fluid dynamics; breakup; surface tension;

   Abstract : Paint and surface treatment processes in a car paint shop are to a largeextent automated and performed by robots. Having access to tools thatincorporate the flexibility of robotic path planning with fast and efficientsimulation of the processes is important to reduce the time required forintroduction of new car models, reduce the environmental impact and increasethe quality.

7. 5. Modeling and simulation of rotary bell spray atomizers in automotive paint shops

   Author : Björn O Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray painting; computational fluid dynamics; atomization; multiphase flow; breakup; coating; surface tension;

   Abstract : The paint and surface treatment processes in automotive paint shops are characterized by multiphase and free surface flows, multiphysics interactions, multiscale phenomena, and large moving geometries. The current version of the software for simulation of spray painting developed at the Fraunhofer-Chalmers Centre relies on measurements of droplet size distributions and velocity profiles below the applicator that can be used as input to the simulations.
