3D Finite Element Analysis on a 270m Rockfill Dam Based on Duncan-Chang E-B Model
Finite Element Model (FEM) High CFRD Stress Strain
2011/12/21
Since no super high CFRD with dam height more than 233m been ever built in the world, more problems of 270m high CFRD are still to be explored and solved. The 270m extra high Maji CFRD is to be constr...
Tearing Strength Calculation Model of the Synthetic Leather Base
Synthetic Leather Base Tearing Strength Test Theoretical Calculation Mode
2011/12/14
The synthetic leather base is a composite, with the top and lower layers are nonwovens and the middle is woven fabrics. Firstly, the single rip tearing strength and drawing out resistances of the leat...
A model for fluvial bedrock incision by impacting suspended and bed load sediment
A model for fluvial bedrock incision impacting suspended bed load sediment
2014/4/8
A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load. The erosion rat...
