This work explores the postbuckling behavior of a marine stiffened composite plate in presence initial imperfections. The imperfection shapes are derived from buckling mode and their combinations. Thereafter, these applied to model, nonlinear large deflection finite element progressive failure analyses performed ANSYS 18.2 software. Hashin criterion is employed model plate. effect geometric on ...
Endoscopic evaluation of a 51 year old woman, who had referred with a 6-months complaint of epigastric pain and fullness in the upper abdomen, demonstrated a large polyp in the greater curvature of the middle third of the stomach. The size of the pedunculated polyp was about 25 mm. Polypectomy was done by snar base and diluted epinephrine was injected submucosally and in to the stem and polyp r...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...
