Work packages

Work structure defined in the scientific project memorandum.

WP1

Experimental characterization

TC fixture for uniaxial machines; repeatability in multiple facilities; standardized shear campaigns; quantitative comparison between TC and standard methods.

WP2

Numerical simulation

Mesoscale progressive-damage modelling and micromechanical RVEs with cohesive interfaces, matrix non-linearity and XFEM crack evolution.

WP3

Standardization process

Validation of UNE Specification 0074:2023 and development of the associated normative document toward full standardization.

Methods and tools

DIC biaxial test

Experimental mechanics

Quasi-static tests, cruciform specimens, strain gauges and Digital Image Correlation for full-field displacement and strain measurement.

RVE numerical model

Numerical modelling

ABAQUS/FEM, mesoscale progressive-damage models, micromechanics, homogenization, cohesive interfaces and XFEM.
