In Memoriam: Titus de Haan
On the threshold of the new year, just before finalising his study, our student Titus de Haan suffered a fatal accident in Australia.Titus came to the University of Twente after obtaining his degree in Automotive Engineering at HAN University of Applied Sciences, aiming to improve his theoretical skills. His interest in lightweight constructions directed him to the specialisation Production Technology in the Master’s programme Mechanical Engineering. We got to know Titus as a down-to-earth, enterprising student with excellent teaching qualities. His Master's thesis project at Cato Composites Innovations was close to being finished. He chose for an adventure in Australia before completing his study in Mechanical Engineering. To our regret, Titus was kept from taking this next step in his life.On behalf of staff and students of the faculty of Engineering Technology, programme of Mechanical Engineering we wish those near to him immense strength to cope with this terrible loss.

Main project actors within Production Technology are Bert Rietman, Laura Vargas, Ivo Vroojink, Muhammad Niazi, Johan van Ravenhorst and Remko Akkerman.
Muhammad Niazi wins the ESAFORM PhD Prize for Industrial Research
Dr. M.S. Niazi has been awarded with the ESAFORM PhD Prize for Industrial Research. He successfully defended his PhD last year in December from the Faculty of Engineering & Technology, University of Twente.The ESAFORM PhD Prize for Industrial Research intends to distinguish a confirmed researcher/designer or a group of industrial researchers/designers, who have brought an outstanding contribution in the field of industrial materials forming. This contribution may lead to a (potential) innovation in design, control or performance of industrial materials processing.
The PhD of Dr. M.S. Niazi relates to continuum damage modeling for sheet metal forming applications in Advanced High Strength Steels (AHSS). Development of AHSS is an important step in reducing the automobile weight. However, plastic deformation induces damage in AHSS. Damage development is anisotropic by nature and shall be considered anisotropic for accurate failure predictions. In this research, anisotropy in damage has been classified into two categories; Material Induced Anisotropy in Damage (MIAD) and Load Induced Anisotropy in Damage (LIAD).
MIAD is related to the anisotropy in distribution and shape of second phase particles or impurities and is governed by void/crack nucleation. LIAD is related to the loading direction of the material. The phenomenon of MIAD was discovered during this research. This is the first research showing the occurrence of MIAD in AHSS. The Modified Lemaitre’s (ML) anisotropic damage model was developed to account for both kind of induced anisotropies. The model was validated with experiments.
