SeaBrick Public · Surface Load Lab

Simplified demonstration geometry — not for manufacture or contact validation. Dimensionless pitch · arbitrary force units (FU).

A point on the surface

Click anywhere on a brick in the 3D view, or choose one of these seven surface points.

Centre · brick 1Exact location on the display mesh

Load strength 6.0 FU

Height change at the chosen point+0.000 pitch

Ready.

No load applied

The arrow marks the actual force point. A force away from the centre also turns the brick. FU are uncalibrated, relative force units.

Push or pull two bricks horizontally

Choose a neighbour below. Push moves the selected brick toward it; pull moves it away. These are separate force directions, not a release command.

Ready-made examples

Demonstration joint assumptions

Rounded dimensionless parameters; not extracted contact dimensions. Relative bend remains limited to 8°.

Schematic radial play0.003 pitch

Schematic along-axis play±0.005 pitch

Demonstration twist guards—

Use demonstration span-based twist guards

Resistance & deliberate removal

No calibrated material properties or test forces are supplied. These controls remain adjustable behaviour assumptions.

Resistance to bending 0.7

Allow aligned upward removal

Pop-out resistance / joint 3.0 FU

Removal is a separate demonstrator mode. Upward force near the centre may open the joints; angled edge loads may not.

Water & waves

Floating response is a spring demonstration, not a fluid simulation. Wave amplitude, wavelength and period are environmental inputs—not calibrated brick properties.

Water support response 14

Travelling waves

Wave amplitude 0.045 pitch

Wavelength 4 pitches

Wave period 4.5 s

Mouse & view controls

Show flat-start height and point travel

Left-drag or middle-drag rotates. Ctrl + middle-drag pans; Shift + middle-drag zooms. Right-drag or Shift + left-drag also pans. Wheel zooms. A click without a drag selects a surface point.

Reverse horizontal rotation Reverse mouse-wheel zoom

Horizontal rotation is reversed from the previous viewer by default, as requested.

Public display geometry is opaque and uniformly scaled. Dimensions use demonstration pitch, not native millimetres. Joint rules are illustrative; contact and stresses are not solved.

Simulated time0.0 s

At least one knob stays in a groove while each connected pair bends.

Connected

The two bricks remain held together.

0.00°of the 8° relative bend limit

There is room to bend further.

Model's engaged seatOuter

The inner or outer knob may carry the connection. The other can move away; both may not let go during ordinary flex. This display reports the model's constraint, not measured contact force.

Steps held back by solver0

Non-converged steps retain the last valid pose. They are not proof of physical jamming. Numerical tolerances: 0.00012 pitch and 0.00025 radians; demonstration assumptions.

Demonstration geometry notes

Friction, elasticity, fracture, coating thickness, contact stresses and fluid loads are not solved. Geometry alone cannot supply the pop-out force.

Removal / re-seating events

No release events.
