In this paper, the crack growth and variations of stress intensity factor in rotary disks with central hole is studied. For modeling and analyzing samples, the FRANC2D software is used and to predict stress intensity factor, DACE emulator (Design & Analysis of Computer Experiments) is used and, at the end comparison between results of modeling and results of simulator has been done. The emulato...

study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. the process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. by means, abaqus software was applied for the finite elem...

conditional monitoring is prerequisite to prevent severe damage or falling down the trees. problems such as trunk decays, reduces trees resistance against wind and floods. in this study, a mathematical modeling technique is being selected to determine the trees strength against such events. finally, an applicable model for safety factor was created by having numeral (dimensions of crown and tru...

nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...
