Abstract
<jats:p>This is the fourth volume of the concurring series of Reports in Applied Mechanics, which is based on the outcome of the advanced project course TMPM10 in Applied Mechanics at Link¨oping University during the autumn of 2025. The course lay-up is based on several industrial or in-house research related projects within the field of Solid Mechanics concerning fatigue, topology optimisation, structural dimensioning, contacts etc, and Fluid Mechanics concerning fluid dynamics, flow, aerodynamics, heat transfer etc. The students tackle industry or forefront research relevant projects in close collaboration with industry from near and neighbouring regions or the university and work in project groups to solve the given tasks within the time limit of the course. Close collaboration with the industry/university is necessary to define planning, update and feedback for further evaluation at the industry/university. This year there were a total of seven projects performed during the course of 2025, five within Solid Mechanics and two in Fluid Mechanics. Some projects were performed in tight collaboration with industry partners, and had a close application to real industrial problems. The other were related to in-house research projects, pushing the research front forward. New knowledge had to be learned and skills were obtained. This has been a good opportunity for the students to show-off all their gained knowledge and apply it in the best possible way to make innovative solutions in the respective projects. Something they all managed to do with success! Tight deadlines can be vital in the industry, and one project group from the Solid Mechanics track fulfilled all deadlines within time during the course, thus earning a LiU reflector tag. A shining example of meeting deadlines!</jats:p>
