A numerical calculation scheme for stress and its consistent tangent moduli with hyper-dual numbers(HDN) for Ogden-type hyperelastic material model was proposed. The main advantage of this scheme is that once the framework is coded, any Ogden-type hyperelastic material model can be implemented by only re-coding the strain energy density function. In this scheme, the new differentiation method for eigenvalue and eigenvector of the symmetric matrices with HDN were proposed. The proposed method can calculate the eigenvalue and eigenvector in non-real part analytically by using the eigenvalue and eigenvector in real part, in case that all eigenvalues in real part are not multiple root. We implemented the Neo-Hookean model and the Ogden model with the proposed scheme, to confirm the effectiveness and robustness of this method, and applied it to some examples. As the results, it was confirmed that the numerical results of the proposed method showed good agreement with analytical ones.

Recently, a personal ICT (Information and Communication Technology) system is useful for everyday life. In the field of education, research and social contribution activities at higher education institutions, the small-scale ICT systems have also been widely used. Here, we introduce an easy-to-use system built by ourselves, and summarize the practices to the fields of the system. In particular, we focus on the following usage. ・Usage as LMS (Learning Management System) in tuition ・Usage for construction of co-editable site ・Usage for student advising in laboratory ・Usage for work-sharing The system has been built in a cloud server (Amazon EC2 (Elastic Compute Cloud)1) provided by Amazon.com) and a CMS (Content Management System) is being used on it. As CMS, we adopted WordPress 3) on Amazon Linux OS provided by "WordPress powered by AMIMOTO< 2). According to W3Techs 4) and Gigazine 5), the share of WordPress reached 25.0% of websites all over the world. There are cases where it is possible to effectively utilize WordPress built on Amazon EC2 in the field of education, research and social contribution activities. If you think that working efficiency in such fields improves by building the small-scale ICT system in this article, we would like to recommend the aggressive introduction to building the system.
