研究 Research

丸山研究室では，構造物や機械の健全性評価技術の開発・発展を目的として，（超）音波を用いた非破壊評価・モニタリング技術について研究を行っています． 主に，固体中での（超）音波の伝搬や散乱現象の解明や適切な利用のため，数値シミュレーションを活用したアプローチを行っています．
Our research objectives are to develop and advance evaluation techniques for the integrity of structures and machinery. To achieve this, we use numerical methods to elucidate and appropriately use ultrasonic wave propagation and scattering in solids.

    所属希望者へ To Prospective Members

    丸山研究室では構造物の維持管理のための非破壊検査・構造物ヘルスモニタリングに関わる研究をしています．具体的な研究トピックとしては理論的な内容が多く，弾性波動（固体中を伝搬する波）の数値・理論解析を主に行っています．そのため，研究活動では，数学や物理，プログラミングを用います．超音波の計測実験を行う場合でも物理的な考察に重点を置いているため，数学，物理，プログラミングを用いることとなります．プログラミング言語は主にFortranを用いています．
    学士特定課題研究・学士特定課題プロジェクト（卒論）のテーマについては，基本的に教員からいくつかテーマを提示して，その中から学生の希望に合わせて選びます．各学生から希望テーマの提案があれば，そちらを実施することも検討します．
    興味のある方は下記の連絡先から丸山にメールで連絡ください．

    For international students:
    Maruyama Lab. research is related to nondestructive evaluation and structural health monitoring for structures. The specific research topics are mainly numerical and theoretical analyses of elastic waves (waves propagating in solids). Therefore, mathematics, physics, and programming are used in our research activities. Even when we work on ultrasonic measurement experiments, we use mathematics, physics, and programming focusing on physical interpretations. The programming language is mainly Fortran in Maruyama Lab. Please consider IGP(A) and IGP(C) for enrollment (see Science Tokyo webpage).
    For postdocs:
    Please consider JSPS Postdoctoral Fellowships for Research in Japan (Standard Program).
    If you have an interest, please contact me via email.
