This study presents a cost-based optimization model for the design of isolated foundations in cohesive soils. The algorithm not only incorporates safety requirements form ultimate limit state (ULS) and serviceability (SLS) criteria but also deals with economics simultaneously. In that regard, generalized reduced gradient (GRG) method is used purpose to achieve least construction cost an foundat...

This paper presents an erosion interpretation of cohesive granular materials stressed by impinging jet based on the results a micromechanical simulation model. The numerical techniques are briefly described, relying two-dimensional Lattice Boltzmann Method coupled with Discrete Element Methods including simple model solid intergranular cohesion. These then used to perform parametric study plana...
