WORK WITH THE EVIDENCE
After the machine stops moving, does this polyurethane keep the same stress?
A compressed polymer spacer introduces a design question: what does “holding it in place” actually hold constant? Follow measured Task 3 polyurethane curves from loading into relaxation, then inspect the recorded deformation.
20 °C · 33 MPa target · load and hold
- Task 3 · 20 °C · deposited curve 1 · Measured response
- Task 3 · 20 °C · deposited curve 2 · Measured response
- Task 3 · 20 °C · deposited curve 3 · Measured response
Task 3; compression to the 33 MPa target, followed by fixed crosshead. The rise records loading and the later segment records relaxation. Temperature views have different load targets; they do not isolate temperature as the only changed variable.
Uncertainty: No per-point uncertainty, load-cell calibration record or raw acquisition series accompanies these figure CSVs. Three deposited curves show repeat variation; their spread is not a calibrated uncertainty interval.

From response to explanation
Measured response
At 20 °C, deposited curve 1 falls from 32.3476 MPa at its largest saved stress to 29.0363 MPa 588 s later.
These are endpoints in one deposited figure curve, not a material specification or an exact 600 s endpoint.
Teaching calculation
For that curve, dividing the last saved stress by the saved peak gives 0.8976338275; the decrease is approximately 10.24%.
A finite observation window cannot identify equilibrium stress, long-term creep or service life.
Measured response
The corresponding recorded strain changes from 1.891% at the saved stress peak to 1.958% at the final saved point.
Reported strain is retained as deposited. Do not replace it with an exact 2% boundary condition or infer a Young’s modulus from that nominal value.
MAKE THE CONNECTION
The stress falls after loading while the crosshead is held. Which conclusion is supported?
Keep these boundaries in view
- Task 3 polyurethane is the measured commercial resin. It is not the epoxy adhesive or chip encapsulant in the adjoining journeys. No monomers, mixture ratios, cure conversion or full chemical composition are inferred.
- Use reported stress and reported strain labels. These figure exports do not explicitly establish a stress/strain measure convention sufficient for reconstructing engineering-to-true conversions.
- No calibrated uncertainty bands are available. Repeat curves are retained separately; no statistical population is inferred from three curves.
- The paper specifies a 600 s fixed-crosshead hold, while these selected figure exports end 576–594 s after their saved peaks. Do not extend the plotted data to 600 s.
- No temperature slider, time-temperature shift, creep conversion, arbitrary loading-history prediction, adhesive strength, package warpage or lifetime prediction is supported by these views.
- A fit to a normalized finite-window curve would be a chosen mathematical description. It would not establish one molecular mechanism or a transferable relaxation constant.
