Based on the damage evolution formation depicted by kachanov of brittle materials in unitary stress state, in this dissertation, the constitutive equation of nonlinear damage material is given, macroscopically, on the assumption that damage variable is exponential relation to strain, d = ( gy i k ) ", where g is the shear module, k is the damage module and the y is the effective strain, d is damage variable and n is hardening exponent
在kachanov描述的一維應力狀態下的脆性材料的損傷演化模型的基礎上，文中給出非線性損傷材料的本構方程，唯象地假設損傷變量與應變成冪次關系， d ~ * = （ g / k ） ~ n ，其中g為剪切模量， k為損傷模量，為有效應變因子， d為損傷變量， n為硬化指數。 -
Certainly, the security of brittle material causes more and more people ' s attention. how to carry out more effective function test to brittle material, especially the mechanics function test, even further to measure online in active service state seems particularly important and urgent
因而，脆性材料的安全性越來越引起人們的重視，如何更有效的對脆性材料進行性能測試，尤其是力學性能測試，甚至是構件在服役狀態下的在線檢測，顯得尤為重要和緊迫。 -
Moreover, the detailed calculation and contrastive analysis are carried out by using the software ansys. theoretical calculation and testing results show that adopting the connection construction with a hole on the web can alleviate the stress state greatly and transform the failure mode of the connection from brittle fracture to local buckling damage on beam, reduces the possibility of brittle fracture by welding and improve the ductility performance of connection to a great extent
結果表明，採用腹板開孔的節點形式，可以使梁的塑性鉸位置由梁根部向中部偏移，達到了有效控制塑性鉸位置的目的;同時，採用這種節點構造可以改變節點附近的梁截面應力分佈狀態，降低了節點脆性破壞的可能性，使節點的破壞模式從脆性破壞轉變為梁的局部屈曲破壞，很大程度上改善了結構的延性。
