Not an expert in explicit ANSYS, but you need to define what is called a body interaction, not a normal contact (as used say in static). This object looks like this (yellow marking) and you can have a bonded type of interaction between parts/bodies. For more info look on the chapter called (or google this and you will get all the info you need).

methodology of bird-strike analysis of an aircraft wing with the use of Ansys 15.0 & Autodyn as analysis tool. The geometry of wing section, the meshing, connections and material properties are modelled and defined in Ansys 15.0. The bird is modelled in Autodyn using SPH technique with gap size of 1.5mm.

  • The contact-pair consists of the contact between two boundaries, one of the boundaries represents contact, slid and deformable surface taken as contact surface (CONTA-173 in ANSYS) and the other represents rigid surface taken as a target surface (TARGE-170 in ANSYS). Figure 5 shows the geometry of (CONTA173& TARGE170).

    Dec 01, 2010 · The contact status is categorized into three types, namely, sticking (S), contact (C) and near contact (N). The criteria for contact status are within the ANSYS capabilities. The friction coefficient between pad and FG brake disk used is between 0.75 and 1.4.

    Contact Types and Behaviours in Ansys. Choosing the appropriate contact type depends on the type of problem you are trying to solve. If modeling the ability of bodies to separate or open slightly is important and/or obtaining the stresses very near a contact interface is important, consider using one of the nonlinear contact types (Frictionless, Rough, Frictional), which can model gaps and ...

    A two dimensional 2-node surface-to-surface contact is used to represent friction and sliding contact for the deformable surface of billet (ANSYS type CONTA171) and a two dimensional target element is used to model the rigid surface of the die (ANSYS type

    Presumably if you create a surface region within Mechanica (sorry, Simulate) and then mesh it in Simulate to export to Ansys, that will do what you need. Otherwise, one suggestion I've heard is to create a very small step in the surface to force an edge (you can probably then delete the tiny vertical elements within Ansys and 'merge' the two ...

    The contact algorithm chosen to represent the contact between the masonry wall face shell and the steel column and beam flanges was a Lagrangian contact algorithm [Simo and Laursen (1992)] using Surface-to-Surface CONTACT174 and TARGET170 [ANSYS (2002)-b] for the contact and target elements, respectively. The coefficient of friction between the

    The fluidic and thermal transport processes were simulated using the ANSYS Fluent CFD solver. Figure 2 shows simulation results of pressure, temperature and fluid flow in the rabbit ocular model. In Figure 2a, most of the ocular interior is at the maximum pressure of 15 Torr; the pressure drop occurs almost entirely across the outer sheath ...

    Apr 28, 2020 · The analyst then defines a sub-model of the crack growth region. FRANC3D reads the sub-model mesh file and remeshes the sub-model to incorporate the geometry of a crack. The crack geometry and location can be prescribed interactively using the Graphical User Interface (GUI).

The target operating pressure constraint corresponds to a maximum target pre-pressure of roughly 14 bar (200 psi). The main objective was to maximize saturation yield without exceeding the volume and pressure constraints. Due to the 3.22 MeV threshold energy for the 14 N(p,α) 11 C reaction, the ideal target geometry is not range-thick to ...

Apr 09, 2019 · Nowadays, getting the highest efficiency and contact surface in heat transfer in industries such as the construction of heat exchangers has become very important. In this simulation the heat transfer between the desired fluid and the geometry that includes a pipe with a spiral path has been modeled.
