Uniaxial stress compute

uniaxial-stress-compute · version 1.0.0 · Units & sizes · free, no key needed

Compute axial engineering stress and strain from unit-bearing force, area, elongation, and original length.

Use when you need to: compute axial stress · calculate engineering strain · force divided by cross sectional area.

Decide before calling

Read the versioned contract and the supported scope below. Reuse uniaxial-stress-compute@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use uniaxial-stress-compute@1.0.0 for compute axial stress. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• compute axial stress
• calculate engineering strain
• force divided by cross sectional area
• elongation over original length
• convert axial stress units
• calculate microstrain

Not supported

• material strength assessment
• true stress or true strain

Behavior

• Stress is force divided by original area through SI pascals; tensile force is positive and compression negative.
• Engineering strain is elongation divided by original length; lengths share one explicit unit.
• No failure decision or material allowable is supplied.

Input

• force (number, required)
• force_unit (one of "N", "kN", required)
• area (number, required)
• area_unit (one of "m2", "mm2", required)
• elongation (number, required)
• original_length (number, required)
• length_unit (one of "m", "mm", required)
• stress_unit (one of "Pa", "kPa", "MPa", "GPa", required)

Output

• axial_stress (number, required)
• stress_unit (one of "Pa", "kPa", "MPa", "GPa", required)
• engineering_strain (number, required)
• microstrain (number, required)

Limits

• max input bytes: 220
