Models tested in current round

ATS1-4 simple test suite

ATS1-4 models represent 1D, 2D and 3D finite element abstractions of constant section beam with various boundary conditions and loads for which the theory and practice of engineering mechanics are well understood. The models are described using imperial units system.

The physical size of the beam is :

X direction : 16"

Y direction : 4"

Z direction : 2"

The ATS1 model represents a beam (rectangular prism) idealized using “rod” elements (axial stiffness element, no torsional stiffness), with the following characteristics:
•    Isotropic material property
•    1000 lbf axial load in compressive (-x) direction
•    Rectangular coordinate system at origin with model at [0, -2, 1]

The ATS2 model represents a beam (rectangular prism) idealized using “bar” elements (axial and bending stiffness element, no torsional stiffness), with the following characteristics:
• Isotropic material property
• 3 load cases:

1.    axial load in compressive (-x) direction
2.    lateral distributed load in bending (-y) direction
3.    combination of 1 + 2

The ATS3 model represents a beam (rectangular prism) idealized using “shell” elements (membrane and bending stiffness element), with the following characteristics:
• Isotropic material property
• 4 load cases:

1.    axial distributed load in compressive (-x) direction
2.    lateral distributed load in bending (-y) direction
3.    combination of 1 + 2
4.    normal distributed load in bending (-z) direction

The ATS4 model represents a beam (rectangular prism) idealized using “solid” elements (mix of 4-noded tetrahedral, 6-noded pentahedral and 8-noded hexahedral elements), with the following characteristics:
• Isotropic material property
• 3 load cases:

1.    axial loads in compressive (-x) direction
2.    lateral loads in bending (-y) direction
3.    combination of 1 + 2
