Bolted or riveted airframe assemblies are typically modeled as continuous meshes. But advances in meshing and solver technology are changing the way we model these assembly structures. Today, continuous meshes are often replaced by individually meshed parts joined together by some type of connector or interaction definition. These individually meshed parts are typically joined together …
Throughout April and June 2016, MSC will be offering a series of free, hands-on workshops that will teach engineers how to simulate complex manufacturing processes such as forming, joining and welding. In addition to providing an overview of the use of finite element analysis (FEA) in various process simulations, these workshops will give you an opportunity …
At present, most companies use simple hand calculations or results from previous designs to predict loads. Neither of these methods is very accurate. Even small errors in calculating loads create large errors in stress results and very large errors in fatigue life predictions. Accurate loads can be determined by building and testing physical prototypes, but …
MBD software goes much further than kinematics tool by providing large displacement dynamics modeling capabilities that capture the full gamut of real-world complexity. MBD tools overcome the limitations of FEA by modeling rigid bodies, flexible bodies, springs, damper, joints and other mechanical components while substantially reducing the time required both to create and solve the …
Search and rescue operations are extremely dangerous, where even trained men and women face a high risk of injury or death in their effort to save lives. One solution in the face of disasters caused by fires, earthquakes and the like, is designing robots that can reach areas too dangerous for humans. While there are …
Simulation of complex manufacturing processes (like welding) needs to take phase transformations of elastoplastic materials into consideration, in order to account for the microstructural properties in the weld core and HAZ (Heat Affected Zone). Such simulations can predict peak temperatures, residual stresses and weld distortions after cooling. Welding defects like hot cracks can thus be …
