Laboratory Overview
Improvement of Reliability of Mechanical Joining
Strength of mechanical joinings determines the strength of structures even if any materials with high strength were used for the structures. Therefore it is very important to improve reliability of mechanical joinings.In our laboratory, we are investigating fatigue mechanisms for bolted joints and other joints and developing some method to estimate their strengths.
Laboratory Character We are attending many conferences about Strength of Materials and Structures. So students can interact other university students. We have also held the joint seminar with other universities. Students can get good oportunities in our laboratory.
