- Static (Stress) Analysis of a Part
The bracket, made of Alloy Steel, is fixed at the two holes and loaded with a 1000 psi pressure as shown:
- Static Analysis of an Assembly
- Static Analysis with a Mixed Mesh
This lesson shows you how to perform static analysis for an assembly with solid and surface bodies. When both element types are present, you have a mixed mesh.
- Analysis of a Fuel Storage Tank
An aluminum storage tank is partially filled with a fuel of density g = 0.029 lb/in3. The fuel exerts a hydrostatic pressure that varies linearly with depth. A linearly varying pressure (p(y) =gy) is applied to all inner faces of the tank below the fuel surface, where y refers to the vertical distance measured from the surface of the fuel.
- Contact Analysis of an Eyebar Assembly
The eyebar assembly is loaded and supported as shown.
- Large Displacement Contact
Contact problems assume small displacements by default. This lesson demonstrates that this assumption can cause convergence to a wrong solution when the actual displacements are large. Using the large displacement function causes convergence to the correct solution.
- Shrink Fitting of Two Rings
The inner and outer radii of the inner ring are 20” and 22”, respectively. The inner and outer radii of the outer ring are 21.25” and 24.25”, respectively (0.75” interference). The inner ring is in compression and the outer ring is in tension. You calculate the stresses and displacements at the interface and compare the results with the analytical solution.
- Remote Forces
Remote forces are forces that are applied at locations outside of the model. The functionality is illustrated by solving a cantilever beam made of two parts using two methods. In the first method, the cantilever is solved as a regular assembly. In the second method, the part with the force is neglected and the force is applied as a remote force.
- Static Analysis of a Sheet Metal Part
This lesson shows you how to perform static analysis on a sheet metal part.
- Converting Solid Geometry to Surfaces
You can analyze thin solid parts with a shell instead of a solid mesh, without compromising the accuracy of the simulation results. To create surface geometry from a solid part you can offset faces, create mid-surfaces, or convert directly to sheet metal. The software generates shell mesh for surface bodies and sheet metal parts automatically.
- Converting a Thin Solid Body into a Sheet Metal and Surface Body
When many thin solid parts are present in an assembly, you can save analysis time by converting them into sheet metal or surface bodies without compromising accuracy of results.
- Failure Analysis of a Composite Joint (Simulation Premium only)
The composite T-Joint model is subjected to internal pressure on the inner faces of the hollow cylinders. You perform failure analysis of the T-joint for an initial 8-layered [0/45/90/-45]2 laminate. You increase the model thickness to a 16-layered [0/45/90/-45]2s laminate to improve the factor of safety.
- Symmetry Restraints for Solid and Shell Models
The axisymmetric pressure vessel shown in the figure is modeled as a solid and as a shell. Due to symmetry a quarter of the vessel is modeled.
- Using Adaptive Methods
You use adaptive methods to calculate the stresses in a 20 inch square by 1 inch thick plate with a 1 inch radius hole at its center. The hole causes a stress concentration with known theoretical value.
- Analysis of a Pulley Under a Bearing Force
Bearing forces develop in contact areas to transfer forces from one part to another. Although you can solve problems with bearing forces as contact problems as explained in the Contact Analysis of an Eyebar Assembly lesson, it saves time and effort to apply them directly.
- Pliers Defined Using Pins
The set of pliers shown below is used to tighten a bolt. It is desired to calculate the stresses when the process is just starting.
- Analysis of a Basketball Assembly With Bolts
The basketball rim shown is attached to the backboard by four bolts. To tighten the bolts, a pre-load tensile force of 100 lbs is applied to each bolt. A vertical force of 250 lbs is applied to a portion of the rim to simulate the loads that the rim may be subjected to. The lower portion of the backboard is fixed.
- Spot Weld of Automobile Parts
Spot welds are commonly used in the mass production of thin sheet metal structures like automobile bodies. In this lesson, you use the spot weld connector to connect the roof to the side bodies of the car as shown below. The roof is subjected to a normal force and the side bodies are fixed at the bottom.
- Design Check for Connectors
The components of a piping assembly are subjected to a high internal pressure load. You define two sets of bolt connectors and check which bolts can safely carry the load, and which will fail.
- Design Check for a Mixed Mesh Assembly
You perform a design check of an assembly of four components: the roof (sheet metal), columns (surface), beams, and vertical panels (sheet metal). You apply snow load on the roof and a wind load on the vertical panel. The assembly is meshed with a combination of shell and beam elements.
- Static Analysis of a Truss
The model is loaded vertically and restrained as shown.
- Creating Beam Diagrams
The model is loaded and restrained as shown:
- Actuator Mechanism with Connectors
The actuator shown in the figure is driven by a force of 15 lb applied to the plunger. The model should be studied when the actuator piston faces a 500 lb/in resistance from the actuator casing. The base of the mechanism sits on a thick sheet of rubber characterized by 1000 (lbs/in)/in2 stiffness.
