Correlation between tension softening relation and crack extension resistance in concrete

Xiufang ZHANG , Shilang XU ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3,   Pages 323-329 doi: 10.1007/s11709-009-0041-2

Abstract: Changes of the material fracture energy consumption with crack propagation can be described by a crackextension resistance curve, one of the fundamental fracture criteria in crack mechanics.Recently, experimental observation of the fracture behavior in concrete was used to develop a new fracturevariation of the crack extension resistance is mainly associated with the energy consumption in the fracturepoints of the crack extension resistance curve is closely related to the characteristic point on used tension

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 4,   Pages 546-553 doi: 10.1007/s11465-018-0501-2

Abstract:

Fracture toughness measurement is an integral part of structural integrity assessment of pipelinesSuch a test provides high constraint and therefore conservative fracture toughness results.In this review, we present recent developments in low-constraint fracture toughness testing, specificallyusing single-edge-notched tension specimens, SENT or SE(T).Examples are also given of the integration of fracture toughness data from SE(T) tests into structural

study on the confine-stiffening effect and fractal cracking of square concrete filled steel tubes in tension

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1317-1336 doi: 10.1007/s11709-021-0763-3

Abstract: Tension stress in steel-concrete composite is widely observed in engineering design.Based on an experimental program on tension performance of three square concrete-filled tubes (SCFT),the tension theory of SCFT is proposed using a mechanics-based approach.The tension stiffening effect, the confining strengthening effect and the confining stiffening effect, observed in tests of SCFTs are included in the developed tension theory model.
