Essential Ansys Tutorials for Engineering Students

In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object A "two-force member" is a structural component where force is applied to only two points Plesha, M et all (2013).

Agenda

• Hand Calculation

• Modelling 2D Truss

• Applying Sizing Mesh

• Applying Boundary Condition

• Applying Load

• Comparing Simulation Result with Hand Calculation

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Transverse loading is a load applied vertically to the plane of the longitudinal axis of a configuration, such as a wind load.  When a beam is transversely loaded different scenario could happen:

1- The beam will bend and also twist if resultant acts stay away from the shear center axis

2- The beam only bend and no torsion will occur if the resultant force passes through the longitudinal shear center axis

Agenda

• Hand Calculation

• 3D modeling of beam

• Applying sizing mesh

• Applying boundary condition

• Applying Load

• Maximum Principal Stress

• Maximum Shear Stress

A simply supported beam is a type of beam that has pinned support at one end and roller support at the other end. Depending on the load applied, it undergoes shearing and bending. It is the one of the simplest structural elements in existence.

Agenda

• Hand Calculation

• Line beam

• Defining New Material

• Applying simply supported boundary condition on node 

• Applying Load on specific point

  
  

A structural member composed of two or more dissimilar materials joined together to act as a unit. Composite construction is often used in building aircraft, watercraft, and building construction.

Agenda

• Hand Calculation

• Create New Material property

• Create 3D Composite Beam

• Applying Sizing Mesh

• Applying Boundary Condition

• Applying Load

• Comparing Simulation Result with Hand Calculation

A wall mounting bracket is a structure that can be fixed on a vertical wall to keep objects on its horizontal surface. In mechanical engineering a bracket is any intermediate component for fixing one part to another, usually larger, part. What makes a bracket a bracket is the fact that it is intermediate between the two and fixes the one to the other.

•Applying Sizing Mesh

•Applying BC and Load

•Analyzing data

Buckling is characterized by a sudden sideways deflection of a structural member. This may occur even though the stresses that develop in the structure are well below those needed to cause failure of the material of which the structure is composed.

Agenda:

• Hand Calculation

• Applying method mesh

• Using static structural result as an input for linear buckling

• Finding first mode of failure

• Calculating maximum buckling stress base on multiplayer load

A contact is a type of connection between two solid, surface, or line bodies. Contacts can be generated automatically, through the interface generator, or manually. Ansys mechanical offers a rich library of connection technology options to simulate many different type of relationships between faces and edges of solid and surfaces.

Agenda

• Modeling in CAD software

• Importing file into ANSYS

• Applying Mesh

• Applying Boundary Condition & Load 

• Using Auto contact

A contact is a type of connection between two solid, surface, or line bodies. Contacts can be generated automatically, through the interface generator, or manually. An automatically created contact and contact behaviour come with intelligent default settings, but you may want to review them. Meshes from upstream to downstream Mechanical Models are renumbered automatically to avoid any overlap. For every analysis system (mesh), you have the choice between automatic renumbering (default) and manual configuration. If automatic renumbering is disabled, you must ensure that the element/node numbering is unique for each mesh.

Agenda

• Using two mechanical models

• Transferring parts into ANSYS Mechanical

• Apply boundary conditions, loads and solve the model

  
  

Debonding is another type of interface/interphase failure, which is often classified as interfiber failure. It is simply attributed to the nature of the bond between fiber and matrix, whether occurring through a zero-thickness interface or an interphase region. Debonding is simply a loss of physica/chemical connection between the reinforcing material and the matrix. This could occur for part of a fiber, whole fibers, or many fibers.

Agenda

• Seting up properties for debonding separation inside engineering data

• Creating 2D geometry in design modeler

• using contact definitions with cohesive zone material inside Mechanical

Composite fracture occurs at three modes, depending on three loading scenarios. Mode I is an opening or tensile mode, mode II fractures consist of a sliding or shear effect and mode III fractures occur due to a tearing or shear loading effect. This tutorial will only be looking at fracture modes of type I.

Agenda

• Seting up properties for delaminating interfaces inside engineering data

• defining delaminating interfaces

• Alternatively use contact definitions with cohesive zone material inside Mechanical

• Applying Boundary conditions and analysis settings

Adhesive joints attract more attention due to their advantage of enabling the development of lightweight, cost-effective and highly integrated structures with a more uniform load distribution and improved damage tolerance.
