Unconventional friction theory based on the subloading surface concept

A constitutive model for the description of friction phenomena is formulated by incorporating the concept of the subloading surface [Hashiguchi, K., 1978. Plastic constitutive equations of granular materials. In: Proc. US–Japan Seminar Continuum Mech. Stast. Appr. Mech. Granular Materials, Sendai, pp. 321–329; Hashiguchi, K., 1980. Constitutive equations of elastoplastic materials with elastic–plastic transition. J. Appl. Mech. (ASME) 47 (1980) 266–272; Hashiguchi, K., 1989. Subloading surface model in unconventional plasticity. Int. J. Solids Struct. 25 (1989) 917–945] falling within the framework of unconventional plasticity [Drucker, D.C., 1988. Conventional and unconventional plastic response and representation. Appl. Mech. Rev. (ASME) 41 (1988) 151–167], which excludes the premise that the interior of a yield surface is a purely elastic domain. It describes the nonlinear relationship between the normal and tangential tractions on a contact surface. Furthermore, it predicts the gradual progress of sliding displacement with an increase in traction, and thus a judgment regarding the fulfillment of the sliding condition is not necessary. This is in contrast to a conventional friction model with a sliding surface enclosing an elastic domain, in which such gradual progress cannot be described and the judgment is required. Thus, a rough numerical calculation with large loading steps even in the explicit numerical method is allowed in the present friction model. In addition, typical friction boundary value problems are analyzed by the finite element method incorporating the present friction model.

History of the Conception of the Us-Japan Seminars on Polymer Synthesis

When the chairman of this US-Japan Symposium on Polymer Synthesis, Professor Virgil Percec, asked me to tell you how the seminar series was conceived and what was involved in initiating such a successful enterprise, I was very pleased to agree to do so. The thoughtfulness of our Chairman reminded me of the writings of an ancient Chinese philosopher who said: “The one who drinks water should think of he who dug the well.” I am glad that we all are drinking the water! I am presenting here a brief history of the circumstances that led to the US-Japan Seminars on Polymer Synthesis, a cooperative program that I hope will continue for a long time. It was about 25 years ago that the initial idea of a US-Japan Seminar on Polymer Synthesis was realized. This concept led to the very successful first US-Japan Seminar in 1974.
