# Deformation and failure maps for PMMA in uniaxial tension

## TL;DR

This paper develops deformation and failure maps for PMMA under uniaxial tension across various temperatures and strain rates, identifying different material regimes and calibrating constitutive models.

## Contribution

It provides comprehensive deformation maps and calibrated constitutive relations for PMMA near the glass transition, covering multiple regimes and strain rates.

## Key findings

- Identified glassy, transition, and rubbery regimes in PMMA.
- Constructed deformation maps for Young's modulus, flow strength, and failure strain.
- Calibrated constitutive relations for different regimes.

## Abstract

Uniaxial tensile tests are performed on a polymethyl methacrylate (PMMA) grade over a range of temperatures near the glass transition and over two decades of strain rate. Deformation maps are constructed for Young's modulus, flow strength, and failure strain as a function of temperature for selected strain rates. The glassy, glass transition and rubbery regimes are identified, and constitutive relations are calibrated for the modulus and flow strength within each regime.
