Simulation Parameters

In this study, the simulation parameters of the door hinge were investigated in the Z direction to have a correlation between the experimental test and simulation. Tests and simulations were conducted according to the United Nations Economic Commission for Europe Regulation No: 11. The simulation parameters, which are the friction coefficient of contacts, the effect of bush material assignment and effect of production imperfections, were examined respectively by utilizing the implicit solver of Ansys Mechanical Workbench 18 and the force-displacement curves were compared with experimental test results in order to decide the optimal settings of parameters. In a conclusion friction coefficient 0.2, non-linear bush material and realistic geometry model were considered as the optimal parameter settings for correlated Finite Element Model of the hinge.

The City

In the 1960s, Addis Ababa experienced a construction boom, spurred by its new international stature as the seat of both the United Nations Economic Commission for Africa and the Organization of African Unity. Working closely with Emperor Haile Selassie, expatriate architects played a major role in shaping the Ethiopian capital as a symbol of an African modernity in continuity with tradition. Haile Selassie's Imperial Modernity: Expatriate Architects and the Shaping of Addis Ababa examines how a distinct Ethiopian modernity was negotiated through various borrowings from the past, including Italian colonial planning, both at the scale of the individual building and at the scale of the city. Focusing on public buildings designed by Italian Eritrean Arturo Mezzedimi, French Henri Chomette, and the partnership of Israeli Zalman Enav and Ethiopian Michael Tedros, Ayala Levin critically explores how international architects confronted the challenges of mediating Haile Selassie's vision of an imperial modernity.
