1. 1. Hygro-Elastic Deformation of High Pressure Laminates. A Macroscopic Analysis. Theoretical Modelling and Measurements

   Författare :Bijan Adl-Zarrabi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; expansion; elastic deformation; moisture transport; orthotropic; high pressure laminate;

   Sammanfattning : Deformation due to environmental changes in moisture arises in many engineering problems of practical interest. The purpose of this work is to develop a theoretical model for the determination of moisture induced deformations in thin plates made of High Pressure Laminates. LÄS MER

3. 2. Mechanical Characterization of Engineering Materials by Modal Testing

   Författare :Daniel Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material variability; modal testing; non-destructive test methods; damping ratios; timber beams; plastic panels; aluminium panel; elastic constants; concrete curing; wood-based panels; solids; high-strength concrete; anisotropic materials;

   Sammanfattning : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).

4. 3. On mechanical characterization and multi-scale modeling of Lithium-ion batteries

   Författare :Priyank Gupta; Peter Gudmundson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; constitutive modeling; U-shape bending tests; electrochemistry; multi-scale modeling; three-dimensional laminate theory.; Solid Mechanics; Hållfasthetslära;

   Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER

5. 4. Transverse failure initiation in polymer composites

   Författare :Leif Asp; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

   Sammanfattning : Transverse failure is one of the most important failure modes in polymer composites. The phenomenon often causes the first deviations from nonlinear laminate behavior. Also, in pressure vessels and pipes, fluid leakage through a path of transverse cracks is often the limiting design criterion. LÄS MER

7. 5. Matrix and interface effects on microcracking in polymer composites

   Författare :Anders Sjögren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Sammanfattning : An underlying industrial problem for the present work is leakage of pressure vessels. Fluid leakage was confirmed to take place along a path of connected microcracks and delaminations. The thesis is concerned with the micromechanisms for microcracking studied by in-situ optical microscopy of cross-ply laminates. LÄS MER
