MS141 - Advanced Constitutive Models for Failure and Fracture in Systems and Components Including Anchoring, Fastening, and Bonding Applications
Keywords: Brittle and cohesive fracture, Computational Mechanics, Continuum Modelling, Methods for fracture and failure
Understanding and predicting the failure and fracture behavior of engineering systems is a fundamental requirement for the safe and efficient design of modern infrastructure. In particular, components involving anchoring, fastening, and bonding applications represent some of the most challenging cases in this context. These systems are often exposed to highly nonuniform stress distributions, complex multi-axial loading paths, and varying environmental conditions. Furthermore, they frequently involve heterogeneous material compositions, such as combinations of metals, concrete, rock, polymers, and adhesives. As a result, accurately predicting their nonlinear mechanical response, including damage initiation, evolution, and ultimate failure, is an ongoing challenge in computational mechanics and material modeling.
In recent decades, significant progress has been made in the development of advanced constitutive models that are capable of describing such complex material behavior. These models incorporate sophisticated descriptions of material degradation, inelasticity, and fracture processes, often extending beyond classical continuum theories. Higher-order continuum models, such as nonlocal, micropolar, or micromorphic formulations, allow for the incorporation of intrinsic length scales that are essential to capture size effects and damage localization. Moreover, phase-field models for fracture provide a thermodynamically consistent framework for simulating crack initiation and propagation.
This minisymposium is dedicated to the modeling, simulation, and practical application of advanced constitutive models for failure and fracture. Contributions are particularly encouraged in areas including, but not limited to:
• Generalized continuum models (nonlocal, micropolar, micromorphic)
• Phase-field approaches to brittle and ductile fracture
• Strain gradient formulations
• Particle methods, e.g. Material Point Method (MPM) or Lattice Discrete Particle Model (LDPM)
• Discrete crack models, including embedded discontinuities and XFEM
• Robust, efficient, and scalable numerical methods and their implementation
• Applications to real-world engineering problems involving anchoring, fastening, and bonding technologies
We particularly welcome contributions that demonstrate the practical applicability of advanced models to real engineering challenges, bridging the gap between theoretical developments and industrial or structural applications.
