Yantu gongcheng xuebao, 2020 In the numerical simulation of a concrete-faced rockfill dam, to consider the accuracy and efficiency of calculation, the concrete slab can be simulated using fine mesh and the rockfill can be simulated using relatively coarse mesh. Therefore, the proper

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]
, 2016 This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.

Experimental study on effects of gradation on strength and deformation of coarse-grained soil
Yantu gongcheng xuebao, 2017 Eight large-scale triaxial tests on coarse-grained soil with different lithologies are carried out. The effects of gradation on strength, deformation, dilatancy and particle breakage characteristics of coarse-grained soil are discussed.

3D character of backward erosion piping [PDF]
, 2018 Backward erosion piping is an important failure mechanism for cohesive water-retaining structures which are founded on a sandy aquifer. Nowadays, piping research and safety assessments are often based on experimental or numerical modelling using ...

Plastic strain directions of rockfill materials during loading and creeping
Yantu gongcheng xuebao, 2018 The determination of the incremental plastic strain direction (IPSD) is one of the kernels in elastoplastic constitutive models. It is generally assume that the IPSD depends only on the stress states and is not influenced by the stress increments.

Simulation method for crest cracks in high earth core rockfill dams and its application
Yantu gongcheng xuebao, 2020 The crest cracks are the common dangers during construction and operation of high earth core rockfill (ECRD) dams. The occurrence and propagation of the crack increases the safety risk of the project greatly.

Mathematical model for breach of tailings dam due to overtopping and its application
Yantu gongcheng xuebao, 2017 Based on the non-equilibrium continuous equation and momentum equation for water-sand mixture, considering the impact on the variation of sand volume concentration due to the change of breach slope and bed, a mathematical model is established to describe

Spontaneous thermal runaway as an ultimate failure mechanism of materials [PDF]
, 2007 The first theoretical estimate of the shear strength of a perfect crystal was given by Frenkel [Z. Phys. 37, 572 (1926)]. He assumed that as slip occurred, two rigid atomic rows in the crystal would move over each other along a slip plane.

Observation of Damage Growth in Compressively Loaded Laminates [PDF]
, 1983 An experimental program to determine tie phenomenological aspects of composite-panel failure under simultaneous compressive n-plane loading and low-velocity transverse impact [C-75 m/s (0-250 ft/s)] is described.

A mechanism of failure in shear bands [PDF]
Extreme Mechanics Letters, 2018 We have carried out dilatant plasticity simulations to investigate the process of failure inside a shear band. The constitutive model accounts for possibly inhomogeneous flow within the band, void rotation and void elongation. We found that the material in the band may soften with no increase in the void volume fraction.
