Supervisor

Associate Professor / Takahiko KURAHASHI
Assoc.Prof. Kurahashi is a caring teacher. In spite of his busy schedule, he is always available for consultations with students regarding research, job hunting, scholarships, etc. In addition, once a week, there is a debriefing session where the teacher and students discuss their research together, so students can proceed with their research smoothly.

Research Content

We apply computational mechanics to engineering problems, solving inverse problems for design assistance and phenomenon estimation. For example, we study automatic design of structures that maximize stiffness under certain conditions and surface texture shapes of machine parts that minimize the friction coefficient. When analyzing structures and fluid motion by computer, we create calculation programs to analyze them, since general software is sometimes inconvenient. From these processes, we can learn how to formulate and analyze consistently.

A Day in the Lab

In our laboratory, the first to fifth period is core time, and research is conducted during the time when classes are not in session. Also, weekly progress reports and research presentations are given every few months to enhance presentation and communication skills. Master's students participate in international conferences every year to develop their presentation skills in international settings. Other events such as the Nagaoka Fireworks Festival and welcome parties for new students are held as opportunities for interaction within the laboratory.
