creep-mechanics-workflow

creep-mechanics-workflow is a skill for Claude Code, Codex from SFETNI/Deep-Matter-Chem-Skills. It costs 6 tokens per session (5,294 once invoked), scanned A, original, MIT.

A workflow for modelling creep, the slow permanent deformation of a material under sustained load, often made faster by heat. It separates deformation rate, changing stress, damage, and final rupture.

In plain words
What is it for?
Selecting, calibrating, implementing, and checking models for long-term deformation and failure of materials or components under sustained heat and mechanical loading.
Why use it?
It helps avoid treating a fit to one part of a creep test as a complete prediction of component life. It also makes clear which parts of the analysis need evidence from tests, material data, or safety codes.

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

creep-mechanics-workflow 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 12d 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.

Creep Mechanics Workflow

Description

Select, calibrate, implement, and validate creep deformation and rupture models for materials and components under sustained thermomechanical loading. The workflow separates rate prediction, transient deformation, stress redistribution, damage evolution, and rupture so that a secondary-creep fit is not mistaken for a full-life model.

This skill supports scientific and engineering analysis. It does not replace high-temperature design codes, qualified material databases, inspection evidence, or safety review.

Domain Context

Creep is time-dependent inelastic deformation under sustained stress, commonly accelerated by temperature. Whether creep is engineering-relevant depends on material class, microstructure, stress, temperature, time, environment, and loading history; no universal temperature or homologous-temperature threshold defines its onset. [EXPERT REVIEW NEEDED]

A conventional uniaxial creep curve may contain:

  • Primary creep: decreasing strain rate as hardening or internal resistance develops.
  • Secondary or minimum-rate region: approximately steady or minimum strain rate over part of the test; a truly constant regime may be absent.
  • Tertiary creep: accelerating strain from damage, necking, cavitation, microstructural evolution, or increasing true stress, ending in rupture.

These stages are curve descriptions rather than unique mechanisms. Diffusion-controlled creep, dislocation glide/climb, grain-boundary sliding, precipitate evolution, recovery, cavitation, oxidation, and phase changes can overlap. Mechanism maps guide hypothesis formation but do not replace alloy- and state-specific evidence.

Homologous temperature uses absolute temperature, normally T/T_m, but the relevant melting or transformation temperature can be ambiguous for multiphase alloys, ceramics, polymers, and evolving materials. [EXPERT REVIEW NEEDED]

Creep analysis has several distinct outputs:

  • deformation or clearance at a service time;
  • stress relaxation under constrained strain;
  • redistributed multiaxial stress and strain fields;
  • onset and evolution of creep damage;
  • time to a specified strain, crack, loss of section, or rupture event;
  • probability or lower-bound life under material and loading scatter.

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.

creep-mechanics-workflow is a skill published in the GitHub repository SFETNI/Deep-Matter-Chem-Skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 6 tokens to every session and 5,294 once invoked, about $0.0000 per session on Opus 5. 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 2026-08-31.
