The establishment of trial-and-error-less manufacturing enhanced by forming simulations has been strongly desired in industry to shorten the product development period and reduce costs for developing manufacturing systems. Improvement of the predictive accuracy for defect formation, such as fracture and springback, in sheet metal forming is a key to realize trial-and-error-less manufacturing.

The NUMISHEET conference series have been established as a world-class forum through which new ideas and technologies in the area of sheet metal forming simulation are exchanged. The NUMISHEET 2018 conference in Tokyo, Japan, features technical, keynote and plenary sessions and mini-symposiums in diverse sheet metal forming areas including the recently introduced incremental sheet forming and hot stamping, as well as advanced material modeling and testing methods for enhancing the accuracy of forming simulations. One of the most distinguishing features of the NUMISHEET conference series is the benchmark session, during which numerical simulations of sheet formed parts are compared with experimental results from the industry and academia. The benchmark session provides an extraordinary opportunity for networking, for the exchange of technologies related to sheet metal forming and material modeling for the numerical validation of sheet metal forming codes. In the NUMISHEET 2018 conference the validation of polycrystal plasticity analysis will be also included in the benchmark session for the first time in the history of the NUMISHEET conference series.

The conference proceedings will be composed of two volumes for regular and keynote papers and for the benchmarks. Both the volumes will be published by the Institute of Physics (IOP) and will be included in SCOPUS database for a wide scientific dissemination. Publication of special issues in prestigious peer-reviewed international journals is currently planned, and the conference delegates will be invited to submit extended versions of their papers after the conference.

Tokyo, officially Tokyo Metropolis, is the capital of Japan and one of its 47 prefectures. The Greater Tokyo Area is the most populous metropolitan area in the world. It is the seat of the Emperor of Japan and the Japanese government. Formerly known as Edo, it has been the de facto seat of government since 1603 when Shogun Tokugawa Ieyasu made the city his headquarters (quoted from "Tokyo" in “Free encyclopedia Wikipedia” (https://en.wikipedia.org/wiki/Tokyo, last modified at 23 March 2017, at 18:12).

During the conference several social activities and industrial tours will be organized. Please familiarize yourselves with the information provided on the website.

We look forward to meeting you in Tokyo, for the NUMISHEET 2018 International Conference and Workshop on “Numerical Simulation of 3D Sheet Metal Forming Processes”.
