Golf Ball Impact Analysis
This example is a dynamic analysis utilizing the automatic surface contact to simulate the impact of a golf club head and ball. The simulation spans a few thousandths of a second, starting immediately before impact. Initial conditions are a rotational velocity of the club, resulting in a speed of 100 MPH at the club head.
Buckling of a Column with Spot Welds
This Finite Element Analysis (FEA) example illustrates the collapse of a steel column implementing mesh independent spot welds connecting two different channel sections, one box shaped and one W-shaped. Either mesh independent fasteners or breakable bonds can be used for this purpose; this example uses mesh independent deformable fasteners.
Analysis of an Automotive Boot Seal
Boot seals are common in automotive applications such as constant velocity joints and steering input shafts. The compliant seals must accommodate the motions found in angulation of the steering mechanism. A clamped end of the seal will remain in contact with the internal shaft, and the boot will self contact on both inner and outer surfaces. In this Finite Element Analysis example the deformation of the seal driven by a typical angular movement of the shaft is studied, providing demonstration of the finite sliding capability in a 3D deformable-to-deformable contact including self-contact in SIMULIA Abaqus.
Impact of a Water-Filled Bottle
Consumer packaging industry commonly uses simulation to reduce time and cost associated with physical prototyping. A simulation of a drop test where an object falls and impacts a hard surface can be implemented to investigate the object’s response under harsh conditions. This SIMULIA Abaqus example simulates a plastic bottle falling onto a flat, rigid floor, using the smoothed particle hydrodynamic (SPH) method involving a fluid material (modeled using Eulerian elements) interacting with structural boundaries (modeled using Lagrangian elements).
Analysis of a Pipeline Buried in Soil
Oil and gas pipelines are often buried in the ground to provide protection and support. These buried pipelines may undergo loading from relative displacement of the ground along their length, from loading caused by faulting, landslides, slope failures and seismic activity. SIMULIA Abaqus includes a library of pipe-soil interaction (PSI) elements to model the interaction of a buried pipeline with the surrounding soil. The pipeline is modeled in beam or pipe elements, and the ground behavior with the pipe-soil interaction elements which track only displacements at their nodes. One node is shared with the pipeline, and the other represents far-field ground motion. This Finite Element Analysis (FEA) determines the stress state along the length of an infinitely long buried pipeline subject to a large (5 ft.) fault movement.
Axisymmetric Analysis of a Threaded Connection
This simulation of a threaded connection incorporates an initial shrink-fit step to resolve the interference between the threaded connections, then the assembly is held fixed while a friction coefficient is applied by changing friction properties. An internal pressure is applied, and finally a torque is applied to the connection, with friction force output from this torque available in outputs.
Backhoe Connector and Actuator Flexible Multibody Dynamics Example
This Finite Element Analysis (FEA) is a mechanism analysis of a simple backhoe. It is an example of flexible multi-body dynamics incorporating idealized hinged connectors and axial actuators. This model has geometry and mesh for the bucket, stick, boom and swing components. A geometry only representation of the tractor is included for visualization purposes.
Crimp Forming with General Contact
This model simulates crimp-forming and implements the general automatic surface to surface contact capability using a large number of contacting surfaces. This contact algorithm allows very simple definitions of contact. Thousands of crimp joints are found in modern automotive applications, where a multi-strand wire bundle is mechanically joined to an end terminal to provide continuity across the joint.
Conductive, Convective, and Radiative Heat Transfer in an Exhaust Manifold
Heat transfer in engine exhaust manifolds is governed by three effects: conduction through the metal, convection from the hot exhaust gases, and radiative exchange between different parts of the metal surface. This SIMULIA Abaqus example illustrates the computation of the equilibrium thermal state of a manifold subject to these effects. The procedure consists of a single heat transfer step in which the thermal loading conditions are ramped up from zero. The boundary constraints on the manifold flanges are a simplification of those experienced under operating conditions: the temperatures at the cylinder head and the outlet are fixed. Convection due to heat transfer from the hot exhaust is applied at the internal surfaces of the manifold tubes. Radiation is modeled between the internal surfaces of the tubes using several methods: the cavity radiation method, with and without cavity parallel decomposition enabled, and using average-temperature radiation conditions.
Rolling of Thick Plates
Hot rolling is a basic manufacturing technique used to transform preformed shapes into a form suitable for further processing. Rolling processes can be divided into different categories, depending on the complexity of metal flow and on the geometry of the rolled product. Although the forming process is often carried out at low roll speed, this example shows that a considerable amount of engineering information can be obtained by using the explicit dynamics procedure in Abaqus/Explicit to model the process. A steel plate of an original square cross-section of 40 mm by 40 mm and a length of 92 mm is reduced to a 30 mm height by rolling through one roll stand. The radius of the rollers is 170 mm.
Indentation of a Thick Plate
This problem illustrates the use of adaptive meshing and distortion control in deep drawing problems. This Finite Element Analysis (FEA) deep indentation problem consists of a rigid punch and deformable foam blank. The blank incorporates adaptive meshing.
Concrete Wall with Embeds
This example is of a concrete wall for tip-up construction using embedded discrete rebar, and ties between the inner and outer wall. This concrete model utilizes concrete damage plasticity, which can assess damage and degradation due to compressive or tensile stresses. This, combined with load stepping, allows simulation of un-aged concrete through installation and other loading, with later load steps being applied to concrete with local damage.
Topological Optimization of a Gear
This example utilizes TOSCA topological optimization to reduce the area in a steel gear, optimizing stiffness by minimizing the strain energy in the gear as material is iteratively reduced. Topological optimization can be based on existing designs and loads, allowing targeted material reductions to maintain stiffness and durability.
Superplastic Forming of a Rectangular Box
In this example we consider the superplastic forming of a rectangular box. The example illustrates the use of rigid elements to create a smooth three-dimensional rigid surface. A superplastic forming process usually consists of clamping a sheet against a die whose surface forms a cavity of the shape required. A uniform gas pressure is then applied to the opposite surface of the sheet, forcing it to acquire the die shape. The pressure schedule is automatically adjusted to achieve a maximum strain rate of 0.02/sec.
