1. 21. Size effect in wood : Characterization of mechanical properties using digital image correlation method

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Amir Saeidi; Olafur Johannsson; [2023]
   Keywords : compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

   Abstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE

3. 22. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Julia Sundmark; [2023]
   Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

   Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

4. 23. Characterisation of an Additively Manufactured Self-Sensing Material Using Carbon Fibre Sensors

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Alain Williamson; [2023]
   Keywords : Additive Manufacturing; Self-Sensing Material; Carbon Fibre Sensors; Structural Health Monitoring; Space Applications; 3D-Printed Continuous Carbon Fibre Filament; Strain Sensor; Mechanical Properties; Electromechanical Properties; Tensile Strength; Failure Strain; Base Resistance; Gauge Factor; Linearity; Systematic Literature Review; Material Selection; Mechanical Design; Material Development; Feasibility Study;

   Abstract : Increasing demand for structural health monitoring in space highlights the need to make the creation of these systems more accessible. This study investigates the potential of additive manufacturing to achieve this goal by characterizing a self-sensing material made of a commercially available 3D-printed continuous carbon fibre filament.

5. 24. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Felix Hansen; Mathias Berglund; [2023]
   Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

   Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

6. 25. Investigation of the basic mechanics of edge cracking in sheet aluminum forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Hamidreza Bayat; Mohammad Abbasi; [2023]
   Keywords : Open Hole tensile test; Digital Image Correlation; Strain Rate; Istra 4D; Thickness reduction rate;

   Abstract : As technology is developing in all automotive companies, car body designers have also investigated new materials such as composite and aluminum alloys. Designing modern car structures has also created various challenges in the production process, including formability limitations. READ MORE
