Bone tissue is a complex multilevel composite which has the ability to sense ad respond to its mechanical environment. It is believed that bone cells called osteocytes within the bone matrix sense the mechanical environment and determine whether structural alterations are needed. At present it is not known, however, how loads are transferred from the whole bone level to cells. A computational p...

From numerical point of view, analysis and optimization in computational material engineering require efficient approaches for microstructure representation. This paper develops an approach to establish an image-based interpolation model in order to efficiently parameterize microstructures of a representative volume element (RVE), based on proper orthogonal decomposition (POD) reduction of dens...

Microscopic stress and strain partitioning control the mechanical damage behavior of multiphase steels. Using a combined numerical experimental approach, local distributions deformation localization are characterized in carbide free bainitic steel produced by continuous cooling. The microstructure consists bainite (aggregate ferrite thin film retained austenite), martensite blocky austenite. Nu...

Abstract Additive manufacturing enables the fabrication of strut-based lattices that consist periodic representative volume elements (RVE) and can be used as cores in sandwich panels. Due to design freedom provided by additive manufacturing, lattice strut diameter may vary through lattice. Thus, distribution adapted stress variation core achieve an efficient avoid oversizing core. Such grading ...

Predicting the nonlinear mechanical response of short fiber reinforced composites (SFRCs) is a crucial and challenging task. In this paper, computationally efficient multi-scale strategy proposed to predict anisotropic elasto-plastic behavior SFRCs using intrinsic pure polymer fibers without requirements for reverse engineering. doing so, different simple unit cells are first examined find one ...

Paper is a complex material consisting of network cellulose fibres at the micro-level. During manufacturing, dried under restraint conditions due to tension in paper web machine direction. This gives rise internal strains that are stored produced sheet. Upon exposure moisture cycle, these may be released. results permanent shrinkage cause instabilities such as curl or waviness The prime objecti...
