MPa. Bending strength of composite is increased obviously compared with that of zirconia because the prestress of surface is compressive stress.关键词:...Prestress Design of Stainless Steel Fibers/Zirconia Composite by Tape Casting赵康School of Materials and Engineering, Xi’an University of Technology摘 要: redistribute internal stress in a prestressed component, the compressive prestress in concrete and the tensile stress in prestressed reinforcement may be reduced. To calculate prestress loss precisely...J. Cent. South Univ. (2016) 23: 470-478 DOI: 10.1007/s11771-016-3092-2 Coupling model for calculating prestress loss caused by relaxation loss, shrinkage, and creep of concrete CAO Guo-hui(曹国辉)1, HU......Coupling model for calculating prestress loss caused by relaxation loss, shrinkage, and creep of concrete
