Since the beginning of the industrial age, material performance and design have been in the
midst of innovation of many disruptive technologies. Today's electronics, space, medical …

This article focuses on computational multiscale methods for the mechanical response of
nonlinear heterogeneous materials. After a short historical note, a brief overview is given of …

Many multiscale finite element formulations can become computationally expensive
because they rely on detailed models of the element's internal displacement field. This issue …

The existence of a representative volume element (RVE) for a class of quasi-brittle materials
having a random heterogeneous microstructure in tensile, shear and mixed mode loading is …

Abstract Nitrate Ester Plasticized Polyether (NEPE) propellant has been widely used for
carrier rockets. However, the propellant is usually subjected to complex loads, changing the …

A cohesive surface theory of fracture is a phenomenological continuum framework that is
closely related to classical fracture mechanics. As such it shares the advantages and …

A new manifold-based reduced order model for nonlinear problems in multiscale modeling
of heterogeneous hyperelastic materials is presented. The model relies on a global …

The modeling of the deformation and failure process of a cyclotetramethylene tetranitramine
modified double-base (HMX-MDB) propellant based on the microstructure is of great …

In this paper, we present the implementation of a small library of three-dimensional cohesive
elements. The elements are formatted as user-defined elements, for compatibility with the …

The development of new generations of propellants with better energetic properties may be
hampered by unsatisfactory mechanical behaviors in terms of strength and toughness. A …
