2. 1. Dynamic higher order equations for structural elements

   Author : Hossein Abadikhah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eigenfrequency; Micropolar; Series expansion; Beam; Plate equations; Torsion;

   Abstract : The subject of this thesis is to derive and evaluate governing equations and corresponding boundary conditions for solid isotropic cylinders and isotropic micropolar rectangular plates. This is achieved by a systematic power series expansion approach, by either adopting a generalized Hamilton's principle or a direct approach. READ MORE

4. 2. Dynamic higher order equations

   Author : Hossein Abadikhah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torsion; Series expansion; Elasticity; Micropolar; Functionally graded material;

   Abstract : The subject of this thesis is to derive and evaluate governing equations and correspondingboundary conditions for solid cylinders and rectangular plates, where the materialconstituting the cylinder or plate are governed by classical elasticity, micropolar elasticityor a functionally graded case of the previously mentioned models. This is achieved by asystematic power series expansion approach, by either adopting a generalized Hamilton'sprinciple or a direct approach. READ MORE

5. 3. Micropolar interface models for microsystem interconnections

6. 4. Modelling and Reliability Assessment of Microsystem Interconnections

   Author : Yan Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone model; discontinuous regularization; Micropolar theory; homogenization; microsystem interconnection;

   Abstract : With the continuous increase of packaging density, the electronic component size and, in particular, the thickness of the involved interconnections decrease significantly. In addition, the microsystem interconnects usually include even finer internal structures. READ MORE

7. 5. Nonlinear micromechanics of open-cell cellular solids

   Author : Per Hård af Segerstad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FEM; Finite strains; Foams; Micropolar theory; Constitutive modelling;

   Abstract : An approach for modelling the response of open-cell cellular solids at finite strainsis developed. The model framework comprises a mechanistic formulation wherethe cellular solid is considered as a network of struts, each connecting two vertexpoints. READ MORE
