Week 1 Stress Concentration on a Plate with hole

model	deformation(m)		stress(Pa)	stress(Pa)
	maximum	minimum	maximum	minimum
plate with hole at center (model 1)	2.6176e-007	0	6.0614e+005	11430
plate with at center and 90 mm apart (model 2)	2.8302e-007	0	5.8219e+005	1564.3 ojectives:

• find out deformation stress and strain in given model with 300*120*30 with hole at center of 60 mm dia
• find out deformation stress and strain in given model with 300*120*30 with hole at center of 60 mm dia and 30 mm dia hole at each side 90 mm apart
• comapare maximum deforamtion stress in both model and find out best one

findings:

second model has maximum deformation of 2.8302e-007 m which is morethan that of model 1, so for a design which required less deforamtion , i will sugest as first model as best

but in second model maximum stress is less than that of first model.for a design which looking for less stress second model is good
