TEC - Thermal Expansion Calculator

Thermal Expansion Calculator is an interactive Chrome extension for students, engineers, and anyone working with materials under temperature changes. Enter basic material properties and instantly compute: • Expansion length (ΔL = α · L · ΔT) • Stress and reaction force if constrained • Strain under temperature changes • Overstress detection (failure check) Key features: • Supports both free and constrained expansion conditions • Compare multiple materials side by side • Visual bar charts to make results intuitive • Lightweight and accessible directly from your browser toolbar This extension combines accurate engineering formulas with a modern, responsive interface built on Next.js and shadcn/ui. It’s a fast, practical tool for classroom learning, quick engineering checks, or exploring how different materials behave when heated or cooled.
