1. 1. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

   University essay from KTH/Lättkonstruktioner

   Author : Ming Kai Chea; [2019]
   Keywords : ;

   Abstract : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.

3. 2. Residual Stresses Induced by Welding in High Performance Steel

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Rebecca Erlingsdotter Stridsman; Felicia Månsson; [2018]
   Keywords : Residual Stresses; High Performance Steel; Heat transfer; Abaqus; Welding;

   Abstract : Today, high performance steel as a construction material is treated as conventional steel in the European standards. Referring to the Eurocodes, the buckling curves for dimensioning of steel constructions only presents values up to steel grade S460, meaning that the full potential of high performance steel is not considered.

4. 3. Difficulties in FE-modelling of an I-beam subjected to torsion, shear and bending.

   University essay from KTH/Byggvetenskap

   Author : Miriam Alexandrou; [2015]
   Keywords : Difficulties; FE-modelling; I-beam; shear; torsion; bending; ABAQUS;

   Abstract : In this thesis six different models of IPE240 have been created in order to study their behavior undershear, bending and torsion. These models simulate IPE240 but differ in the boundary conditions, inthe loading and the length of the beam and in some connections which connect certain elements. READ MORE

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Aliasgar Hirani; George John; Henry Mupeta; [2015]
   Keywords : buckling curves; buckling resistance; Eigen-value; Eurocode 3; flexural;

   Abstract : This work focuses mainly on the resistance of members to flexural buckling according to Eurocode 3. The work provides the mathematical backgrounds to the equations and buckling curves presented in Eurocode 3. READ MORE

6. 5. Mechanical properties of carbon nanotubes grown by pyrolysis of ferrocene

   University essay from Fakulteten för teknik- och naturvetenskap

   Author : Sofie Yngman; [2012]
   Keywords : Carbon Nanotubes; Mechanical properties; Scanning electron microscopy; Atomic force microscopy; Youngs modulus; transmission electron microscopy;

   Abstract : Carbon nanotubes (CNTs) have drawn a lot of attention during the last decades due to its promising mechanical and electrical properties. Extensive research regarding the mechanical properties of CNTs has been carried out during the last decades. READ MORE
