StressScale: Stress & Strain

StressScale is a comprehensive engineering tool designed for precise stress and strain analysis. Built for engineers, students, and materials scientists, this utility provides the calculations and visualizations necessary to understand material behavior under tensile load.
Accurately determine the difference between engineering metrics and true physical behavior. As materials undergo significant deformation, the cross-sectional area changes—StressScale accounts for these variations to provide true stress and strain values that initial area calculations often overlook.
Key Features:
• True vs. Engineering Stress: Compare results based on initial (A₀) and instantaneous (Aᵢ) cross-sectional areas for a complete picture of material performance.
• Interactive Visualization: Observe the necking effect through an animated specimen model that dynamically adjusts based on your input dimensions and elongation.
• Safety Analysis: Get instant Factor of Safety (FoS) calculations. The app identifies if your material is within the elastic region or has reached the plastic deformation stage.
• Material Database: Access pre-loaded mechanical properties for common engineering materials, including Steel (A36), Stainless Steel (304), Aluminum (6061-T6), Copper, and Titanium.
• Custom Specifications: Input your own yield strength and properties for custom alloys or experimental materials.
• Dual Unit Support: Seamlessly switch between Metric (mm, N, MPa) and Imperial (in, lbf, PSI) systems with high-precision decimal support.
• Detailed Metrics: Calculate engineering strain, true strain, and the percentage reduction of area to evaluate material ductility.
• History Management: Maintain a searchable database of previous tests. Review, compare, or delete old records as needed.

StressScale streamlines complex mechanical calculations into a clean, functional interface, making it an essential companion for laboratory testing, structural design, and academic study.
