16. Finite Element Modeling of Short, Randomized Fiber Composite Material
Master-uppsats, KTH/LättkonstruktionerSammanfattning : With the advent of hybrids and electric vehicles, the need for lightweight and highperformancematerials is growing. Sheet molding compound (SMC) is a compositemade of short and randomized bers that o ers a substantial weight reduction andgood mechanical properties while meeting the demand for large volume production.

17. Prediction of paperboard thickness and bending stiffness based on process data
Master-uppsats, KTH/Hållfasthetslära (Avd.)Sammanfattning : Bending stiness is one of the most important mechanical properties in paperboard making,giving rigidity to panels and boxes. This property is currently only possible to measure bydestructive measure o the production line. LÄS MER
18. Simmulating pullout forces in particleboard
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. LÄS MER
19. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/ByggnadsmekanikSammanfattning : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

20. Finite element analysis of e-commerce cushioning in corrugated board
Master-uppsats, KTH/Hållfasthetslära (Avd.)Sammanfattning : Corrugated board and other paper products are widely used in product packaging due to good mechanical properties, recyclability, price etc. Due to the growing e–commerce industry the dynamical behaviour of corrugated board is of particular interest. Paper exhibits an orthotropic behaviour and is a non–linear material. LÄS MER
