Contact and glue conditions for MSC Nastran

In the MSC Nastran environment, use the General Contact/Glue command to model either general (touching) contact or glued contact between faces or bodies. For example, you can use analyze contact stresses between touching or glued bodies. For example, you can use the General Contact/Glue command to analyze contact stresses between touching or glued bodies.

Defining a glue connection

You can use the Glue option in the Local Geometric Contact Parameters modeling object dialog box to specify whether you are creating a glued connection and, if so, which type of glued connection. The Glue option is helpful when you have separate surfaces that you need to tie or glue together to prevent any relative motion between them.

Contact and glue commands

Command	Description	MSC Nastran syntax
General Contact/Glue simulation object	Lets you define contact and glue conditions in a solution or a solution step.In Solution 101 analyses, you can include a General Contact/Glue object at the solution level or at the step/subcase level.In Solution 103 analyses, you can include a General Contact/Glue object at the solution level only.	BCONECT bulk data entryBCONTACT case control commandBCTABL1 bulk data entry (created automatically if your input file contains multiple General Contact/Glue simulation objects)
Region command	Lets you specify the faces and bodies that participate in the contact or glue definition.Pre/Post supports the DEFORM option only for the region's behavior, which means all contact regions are deformable.Pre/Post supports the 3D dimension option only, which means that the contacting bodies are 3D bodies that are composed of rigid surfaces, solid elements, or shell elements.	BCBODY1 bulk data entryBSURF bulk data entry
Local Geometric Contact Parameters modeling object	Lets you define the geometric contact parameters that MSC Nastran uses to determine whether contact occurs between bodies in the analysis.	BCONPRG bulk data entry
Global Geometric Contact Parameters modeling object	Lets you specify contact parameters at the solution level.	BCPARA bulk data entry
Physical Contact Parameters modeling object	Lets you define the parameters that control physical contact in Solution 101 analyses only.	BCONPRP bulk data entry
Contact Body Parameters modeling object	Lets you define structural and thermal parameters for contact body pairs in a Region in Solution 101 analyses.	BCBDPRP bulk data entry
