    Revisiting classical concepts of Linear Elastic Fracture Mechanics
    2024/12/27
    The audio deep dive explores linear elastic fracture mechanics, analyzing how mathematical models predict crack behavior. Key concepts such as the mathematical crack, stress intensity factors (SIFs), and contact stresses are discussed, highlighting how classical models can lead to impossible overlaps. The analysis also includes the effects of material properties, different loading modes, and stress neutralization techniques. The deep dive emphasizes the importance of refined models and damage tolerance in engineering design.

    ESIAM23: an interview with Jan Torgersen
    2024/12/27
    The interview with Yan Torgersen highlights the advantages of additive manufacturing in the energy sector. Torgersen notes that additive manufacturing uses only the material needed for printing, which reduces waste, and this is a significant benefit in the energy sector, where there is often a lot of waste. Additionally, additive manufacturing provides the geometric freedom to design transport paths inside electrochemical or electrical structures. With the advent of electrically conductive micro and nanoscale devices, additive manufacturing is considered a game changer.
