چکیده

Abstract This research work highlights the prediction of hardness behaviour age-hardened LM4 and its composites fabricated using a two-stage stir casting method with TiB2 Si3N4. MATLAB - Artificial Neural Networks is used to predict age-hardening composites. Experiments (hardness tensile tests) are conducted collect data for training an ANN model as well investigate effect reinforcements treatment on The results show that increment in reinforcement wt.%, there enhancement ultimate strength (UTS) values within monolithic As-cast hybrid display 37 54% improvement compared as-cast LM4. Heat-treated samples, specifically those treated peak aging MSHT 100°C aging, perform better than samples other heat-treated terms UTS hardness. Compared LM4, MSHT, aged 85 202% VHN. Hybrid hardness, while 3 wt.% (L3TB) UTS, (MSHT aging) L3TB 68% when developed trained five inputs (wt.% TiB2, Si3N4, type solutionizing, temperature, time) one output (VHN) different algorithms number hidden neurons age hardening Among them, Lavenberg-Marquardt (LM) algorithm normalized 30 performs shows least average error 1.588364. confirmation test confirms can %error 0.14 unseen data.

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Prediction of the deformation modulus of rock masses using Artificial Neural Networks and Regression methods

Static deformation modulus is recognized as one of the most important parameters governing the behavior of rock masses. Predictive models for the mechanical properties of rock masses have been used in rock engineering because direct measurement of the properties is difficult due to time and cost constraints. In this method the deformation modulus is estimated indirectly from classification syst...

Rock Brittleness Prediction Using Geomechanical Properties of Hamekasi Limestone: Regression and Artificial Neural Networks Analysis

The cold climate is a favorable parameter for the development of tension cracks and decrease of rock brittleness. Therefore, this paper attempts to investigate the Hamekasi porous limestone in order to predict the brittleness indices during freeze-thaw cycles. The freeze–thaw test was executed for one cycle including 16 h of freezing, and 8 h of thawing. The geo mechanical properties and brittl...

Prediction of Permanent Earthquake-Induced Deformation in Earth Dams and Embankments Using Artificial Neural Networks

This research intends to develop a method based on the Artificial Neural Network (ANN) to predict permanent earthquake-induced deformation of the earth dams and embankments. For this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. In order to predict earthquake-induced deformation o...
