| 1 | A plastic damage model for concrete structure cracks with two damage variables显示文摘Based on the concepts of continuum damage theory,a new plastic damage model for concrete crack failure is developed through studying the basic damage mechanics.Two damage variables,tensile damage variable for tensile damage and shear damage variable for compressive damage,are adopted to represent the influence of microscopic damage on material macromechanics properties under tensile and compressive loadings.The yield criteria and flow rule determining the plasticity of concrete are established in the effective stress space,which is convenient to decouple the damage process from the plastic process and calibrate material parameters with experimental results.Meanwhile,the plastic part of the proposed model can be implemented by back-Euler implicit algorithm,and the damage part is explicit.Consequently,there exist robust algorithms for integrating the constitutive relations using finite element method.Comparison with several experimental results shows that the model is capable of simulating the nonlinear performance of concrete under multiaxial stress state and can be applied to practical concrete structures. | ZHENG FuGang WU ZhongRu GU ChongShi BAO TengFei HU Jiang | 2012 | Science China(Technological Sciences)2012，55，11： | 6 |

| 3 | Effect of interfacial delamination on coating crack in thick diamond-like carbon coatings under indentation显示文摘Coating crack and interfacial delamination are recognized as two critical factors inducing spallation of thick diamond-like carbon(DLC)coatings.The effect of the two factors is found to dramatically accelerate the failure of thick DLC coatings.However,there are few reports on the effect of interfacial delamination on coating crack.In this work,in order to investigate the evolution of the coating crack and interfacial delamination,as well as the effect of interfacial delamination on coating crack,a finite element model that combines the bilinear cohesive zone model and the extended finite element method(XFEM)is established.It is found that the occurrence of interfacial delamination triggers a second expansion of coating crack.Factors influencing the degree of interfacial delamination on coating crack can be modulated by coating thickness and coating elastic modulus.As the coating thickness increases,the length of interfacial delamination increases,and thus the propagation of coating crack is accelerated.In contrast,the increase of coating elastic modulus could reduce the length of interfacial delamination,which consequently weakens its influence on the propagation of coating crack. | Zhongbao Wang Xiangli Zhong Limei Jiang Fugang Qi Xiaoping Ouyang Jinbin Wang Bin Liao Jun Luo | 2020 | Acta Mechanica Sinica2020，36，2： | 0 |
