A Complete Methodology for Structural Finite Element Analysis of Terracotta Sculptures Based on a 3D Scanned Model: A Case Study on the Terracotta Warriors (China)
ABSTRACT In this paper, the structural mechanical analysis of the Terracotta Warriors, using 3D laser scanning technology and finite element methodology (FEM) is presented. The workflow of the case study mainly includes three steps along with the application of different software. The first step is to capture the point cloud using a 3D laser scanner and the reversed modeling using Geomagic Studio. Next, the model is imported into Hypermesh to accomplish mesh generation. Finally, the meshed model is imported into ABAQUS for analysis. The workflow constitutes an innovation for introducing a mesh generation method that is commonly used in biomechanics by Hypermesh, software that offers benefits such as functional and simple operation. In the analysis, cases such as sculpture at different incline angles to the ground and some particular conditions are included. The results indicate that apart from the ankle, the thigh and hip joints also remain in an adverse position under gravity. Given that the ground for storage and exhibition is not ideally flat, the stress on the whole structure can be reduced by rotating the sculpture at an appropriate angle.
期刊介绍：
Studies in Conservation is the premier international peer-reviewed journal for the conservation of historic and artistic works. The intended readership includes the conservation professional in the broadest sense of the term: practising conservators of all types of object, conservation, heritage and museum scientists, collection or conservation managers, teachers and students of conservation, and academic researchers in the subject areas of arts, archaeology, the built heritage, materials history, art technological research and material culture.
Studies in Conservation publishes original work on a range of subjects including, but not limited to, examination methods for works of art, new research in the analysis of artistic materials, mechanisms of deterioration, advances in conservation practice, novel methods of treatment, conservation issues in display and storage, preventive conservation, issues of collection care, conservation history and ethics, and the history of materials and technological processes. Scientific content is not necessary, and the editors encourage the submission of practical articles, review papers, position papers on best practice and the philosophy and ethics of collecting and preservation, to help maintain the traditional balance of the journal. Whatever the subject matter, accounts of routine procedures are not accepted, except where these lead to results that are sufficiently novel and/or significant to be of general interest.
