I have few confusions in the results. First of all since its an axisymmetric model. i have applied constraints (displacement y=0) only on the bottom of the model. but results shows that the stresses are not evenly distributed from top to bottom. Should i apply constraints y=0 on the top as well.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/37c35be4-48eb-438f-9d0a-a99b015a4448\/32723257-e2a9-4556-842a-aa2500fe632a_stress.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Second I need to check if the stresses produced due to high internal pressure stays under the yield stresses of the material. the normal stresses are a lot different than the equivalent stresses. Which stresses should i consider in my analysis.
