New Approach to Obtain an Optimal Value for MQ-RBF Shape Parameter for the Nonlinear Analysis of Elastic Thin Plate- Juniper Publishers

 Civil Engineering Research Journal- Juniper Publishers   Abstract A new approach in using a multi-quadric radial basis function (MQ-RBF) in the analysis of nonlinear behaviour of elastic thin plate is provided. The approach provides a new method to obtain an optimal value of the shape parameter, c, involved in the (MQ-RBF). The shape parameter c plays a very important role in the accuracy and stability of the solution. The approach uses approximate exact linear solutions of linear analysis of the thin plates as standpoint toward the calculation of the optimal c value. Then, the optimal c values were implemented in the analysis of nonlinear thin plate behaviour. Combinations of different boundary conditions (simply, and clamped), for a square thin plate under uniform distribution loads were analysed. The accuracy of the adopted approach has been validated by comparing the results with FEM solutions. The comparison shows that the approach can be used effectively in obtaining the optimal

Integrated Solution to the Problem of Resource-Saving Fixing of Moving Sands- Juniper Publishers

Image
 Civil Engineering Research Journal- Juniper Publishers   Abstract Movable sands, which occupy large areas around the world, are becoming more intensively developed, but their susceptibility to deflation causes the problem of dispersal, transfer and deposition of sands that impede the normal operation of engineering facilities. Science and practice have offered many solutions, but they are far from perfect from the point of view of economic and environmental. A comprehensive resource-saving solution to the problem is proposed based on: the priority of the physicochemical method of fixing and using a water-soluble binder; pre-moistening of sand, which allows significant savings in consumption of the binder and its working composition, as well as extending the production time of work and the use of material and human resources; laconization of research methods; use of waste and related products of local production, two of which are studied in this work.
