This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, that is, an infinitely rigid one, a cavity and an elastic inclusion. This formulation can be useful when the scatterer is in the far field of the source, so ... Read More
In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... Read More
This example demonstrates how to model coupled flow, heat transfer, and structural deformation and stress in a pipeline network. Gravity loads from the pipe and fluid are also taken into account. Read More
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... Read More
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Read More
This model shows how to use the scattered-field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite-size phononic crystal. The transmission tends to zero in the frequency ranges corresponding to P- and S-wave band gaps, as ... Read More
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Read More
Coupling acoustics in liquids or gases with structural mechanics has applications in many engineering fields, including loudspeakers, acoustic sensors, nondestructive testing, and medical ultrasound diagnostics. This tutorial model demonstrates how to model the interaction between sound ... Read More
This example shows how to use response spectrum analysis to verify the integrity of a structure that is exposed to an earthquake. The building is modeled as a steel frame, using beam elements. Displacements and stresses are computed. Read More
Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite ... Read More
