I am performing a static analysis on a wing of an aircraft. A problem that I am encountering is the modelling of solid elements with shell elements.October 21, 2020 at 1:42 pmRahul KumbharAnsys EmployeeYou can try different settings in 'Constraint type' in Bonded contact advanced options to check wich one gives better result. Probably 'Distributed, inside pinball egion' could work best. nOctober 22, 2020 at 7:58 ampurichmunlowSubscriberThank you for your suggestion! I appreciate it. I tried all the options that you suggested but still did not work out. Any other suggestions you could provide? Any other ways to model this?nOctober 22, 2020 at 12:09 pmRahul KumbharAnsys EmployeeAny reason you believe its not working? Are you just checking highest stresses in the model. There can be the other reasons for higher stress like large deflection is off, or linear material. The contact area is very close to the support. You should have very fine mesh both on solid face as well shell edge in contact.nTo check if the contact is properly working or not, you should plot the stress on the contact face. The bending stress should look symmetrical on the contact face.nOctober 22, 2020 at 2:34 pmmzhossain2001SubscriberIt is always better to apply similar dof elements at the joints. May be shell to shell or solid to solid. Other than that, If other methods are used like MPC or CE, or coupling - then you need to test your model very carefully, for ensuring the accuracy of the results. Basic FEA fundamental theories shall be applied to get the correct result. There is no shortcut to that.nViewing 4 reply threads
