Concrete Damage Plasticity in ABAQUS (CDP) | Step-by-Step Failure Modelling Tutorial

Concrete Damage Plasticity (CDP) is one of the most powerful — and most misunderstood — material models in ABAQUS. In this video, I provide a clear, step-by-step guide to implementing Concrete Damage Plasticity and complete material failure in ABAQUS, starting from experimental test data and ending with element deletion and visualised cracking. 🎯 What this tutorial covers: • Defining elastic properties for concrete • Input of compressive crushing and tensile cracking data • Using cylinder / cube test results correctly • Damage parameters for stiffness degradation • Plasticity flow parameters and convergence tips • Ensuring monotonic input data (avoiding CDP errors) • Visualising cracking and element deletion • Defining complete concrete failure using keyword editing This tutorial is ideal for civil engineers, researchers, postgraduate students, and FEA users who want physically meaningful concrete failure simulations — not trial-and-error models. 📌 Software used: ABAQUS/CAE 📌 Level: Intermediate to Advanced If this helped you, like, subscribe, and comment below — your question may become the next tutorial.
