Reinforcement calculation of concrete slab in concrete faced rockfill dams

Yantu gongcheng xuebao, 2023
The stress and deformation safety of the concrete slab is crucial to the concrete faced rockfill dams (CFRDs), however, most of the traditional methods do not consider the effects of the reinforcement in slab, therefore, the calculated results can not ...

Damage process modeling on SMC

Journal of Applied Polymer Science, 1996
The damage processes taking place in SMC, which has been subjected to monotonically increasing tensile loads, are analyzed and the stress-strain curves are calculated. SMC is viewed as a laminate consisting of fiber bundles embedded in a resin/filler matrix.
