springback-analysis

springback-analysis is a skill for Claude Code, Codex from Cai-aa/CAE-Agent-Hub. It costs 0 tokens per session (512 once invoked), scanned A, original, MIT.

A guide for modeling springback in Abaqus after a composite part is released from its mold. Springback is the shape change that happens when stored internal forces are freed during demolding.

In plain words
What is it for?
Use it to configure the springback stage, remove the mold contact and tool elements, replace old constraints, and apply the final support condition.
Why use it?
It sets up mold and contact removal so the part can deform under the intended remaining constraint.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

springback-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Springback Analysis

Description

Configure springback analysis with Model Change for mold removal. Invoke when user needs mold removal, springback step, or Model Change setup.

Content

Springback occurs in the sp (springback) step, which is the 4th and final step of the curing simulation. During this step, the mold/tool is removed and the composite part is allowed to deform freely, constrained only at the Set-2 inner corner.

Model Change: Remove Contact Pair

The contact pair between the composite surface and the tool surface is removed:

*Model Change, type=CONTACT PAIR, remove
com-surface, tool-surface

Model Change: Remove Tool Elements

All tool elements are removed from the analysis using Model Change:

*Model Change, remove
_PickedSet329,
  • _PickedSet329 = all tool elements (element numbers 1 to 1672)

Boundary Conditions in sp Step

The sp step uses op=NEW which replaces ALL previous boundary conditions:

  • Previous tool BCs removed: Use an empty *Boundary, op=NEW to clear previous tool constraints
  • New constraint applied: Set-2 is constrained with U1=U2=U3=0
*Boundary, op=NEW
Set-2, 1, 1, 0.
Set-2, 2, 2, 0.
Set-2, 3, 3, 0.

Loads in sp Step

  • Pressure removed: Use *Dsload, op=NEW with no data lines to remove all distributed loads
*Dsload, op=NEW

Temperature

Temperature is maintained at 25°C during the springback step.

Result

After mold removal, the composite springs back freely and is constrained only at the Set-2 inner corner. The springback displacement (U1, U2, U3) at the last frame of the sp step represents the final part shape deviation.

Key Points

  • The sp step is the final step where the part is released from the mold
  • Model Change must remove both the contact pair AND the tool elements
  • Using op=NEW on boundary conditions and loads ensures a clean state for springback
  • The final deformation is captured in the last frame of the sp step
  • This displacement data is used to evaluate part quality and springback deviation

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

springback-analysis is a skill published in the GitHub repository Cai-aa/CAE-Agent-Hub (832 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 512 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
