Route towards power MOSFET large thin die mechanical robustness: Masters thesis report

Today’s cars are undergoing the greatest transformation the industry has seen. Power MOSFETs play a crucial role in making electronics more energy efficient by driving down switching losses and Rdson using a combination of next-generation trench technology and ultra-thin dies. Power MOSFET dies are becoming larger ( > 5 X 5 mm ) and thinner (...

Analytical description of the forming process of a double curvature shipbuilding plate

The forming of double curvature shipbuilding steel plates is performed by experienced craftsmen at IHC Metalix. Their experience will get lost when they retire; therefore, it can be valuable for future metal workers to capture the forming process of a double curved plate theoretically. An analytical description and understanding of the forming...

Calcium phosphate cement reinforced with poly (vinyl alcohol) fibers: An experimental and numerical failure analysis

Calcium phosphate cements (CPCs) have been widely used during the past decades as biocompatible bone substitution in maxillofacial, oral and orthopedic surgery. CPCs are injectable and are chemically resemblant to the mineral phase of native bone. Nevertheless, their low fracture toughness and high brittleness reduce their clinical...

Experimental and numerical analysis on bending and tensile failure behavior of calcium phosphate cements

Since their discovery in the 1980s, injectable self-setting calcium phosphate cements (CPCs) are frequently used in orthopedic, oral and maxillofacial surgery due to their chemical resemblance to the mineral phase of native bone. However, these cements are very brittle, which complicates their application in load-bearing anatomical sites....

Stem breakage of salt marsh vegetation under wave forcing: A field and model study

One of the services provided by coastal ecosystems is wave attenuation by vegetation, and subsequent reduction of wave loads on flood defense structures. Therefore, stability of vegetation under wave forcing is an important factor to consider. This paper presents a model which determines the wave load that plant stems can withstand before...
