Math & Numbers
平均应力修正下的疲劳安全系数。给定应力幅 σ_a、平均应力 σ_m,以及材料 σ_uts、疲劳极限 σ_-1、屈服 σ_y,输出三种经典判据的安全系数:Modified Goodman(线性保守)、Gerber(抛物线,更贴合延性材料)、Soderberg(用 σ_y,最保守)。取三者最小值为控制值,并判定工作点是否在 Haigh 图 Goodman 线内侧。
用三种语言从你的代码中调用此工具。
curl -X POST 'https://api.elysiatools.com/zh/api/tools/fatigue-limit-calculator' \
-H 'Content-Type: application/json' \
-d '{"stressAmplitude":100,"meanStress":200,"uts":800,"enduranceLimit":300,"yield":500,"decimalPlaces":4}'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
POST https://api.elysiatools.com/zh/api/tools/fatigue-limit-calculator| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| stressAmplitude | number | 是 | Alternating stress amplitude σ_a = (σ_max − σ_min)/2 in MPa. Must be > 0 (zero amplitude means no cycling). |
| meanStress | number | 否 | Mean stress σ_m = (σ_max + σ_min)/2 in MPa. Tensile (>0) reduces fatigue life; compressive (<0) is beneficial but unusual in textbook problems. |
| uts | number | 否 | Ultimate tensile strength of the material in MPa. Required by Goodman and Gerber. |
| enduranceLimit | number | 否 | Fully reversed fatigue (endurance) limit σ_-1 in MPa, typically for 10⁶ cycles or more. Must not exceed σ_uts. |
| yield |
