1. Investigation of Injury Predictors for Rat Neuro Trauma
University essay from KTH/Medicinteknik och hälsosystemAbstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE

2. Rate-dependent effects on the mechanical behaviour of paper
University essay from KTH/HållfasthetsläraAbstract : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. READ MORE

3. Implementation and study of boundary integral operators related to PDE:s in the plane
University essay from Lunds universitet/Matematik LTHAbstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

4. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. READ MORE

5. Validation of An Iteration Free Material Model for Paperboard (NEO)
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE
