Microstructural fields for the 2D elastic microstructure with one circular inclusion. Top row: Fixed and adapted sampling pattern with the same number of wave vectors. Middle row: Corresponding microstructural stress field σ 11 incorporating the reconstruction and compatibility step for the solution of the fixed sampling pattern and only the compatibility step for the solution of the adapted sampling pattern and reference stress field computed with the full set of frequencies. Bottom row: Absolute difference in the microstructural stress field ∆σ 11 .

We present a modified model order reduction (MOR) technique for the FFT-based simulation of composite microstructures. It utilizes the earlier introduced MOR technique (Kochmann et al. [2019]), which is based on solving the Lippmann-Schwinger equation in Fourier space by a reduced set of frequencies. Crucial for the accuracy of this MOR technique i...

Liquid droplets in solid soft composites have been attracting increasing attention in biological
applications. In contrary with conventional composites, which are made of solid elastic inclusions, available material

In the present work, damage propagation in thermoplastic composite laminates subjected to quasi-static tensile loading was numerically simulated using different damage models. The simulation was performed using the commercial finite element suite LS-Dyna, where various material models were evaluated based on their ability to simulate the thermoplas...

During their applications, ferroelectric devices are subjected not only to electromechanical loading but also to thermal fields, inducing additional stresses and impairing their functionality. Additionally, internal heat generation can occur by the dissipation of the inelastic work resulting from ferroelectric hysteresis. Moreover, at extreme elect...
The present research focuses on proposing a novel theoretical micromechanical model (TMM) designed to derive the frequency-dependent storage and loss moduli of woven fabric (WF)-matrix composites, as well as WF-particulate matrix (Hybrid) composites, based on their constituent properties. The TMM serves as a higher-order modulus operator, accountin...
Granular materials show inhomogeneous flows characterized by strain localization. When strain is localized in a sheared granular material, rigid regions of a nearly undeformed state are separated by shear bands, where the material yields and flows. The characteristics of the shear bands are determined by the geometry of the system, the micromechani...
