The effect of width-to-thickness ratio, aspect ratio, number of layers, material anisotropy, load ratios (Ny/Nx), uncertainties in material properties and functionally graded materials on the results is investigated and compared.
Both constant-property materials and functionally graded materials were considered for the interphase.
This modeling approach is applied to simulate the fretting contact involving multilayered materials and functionally graded coatings and to unfold the dependence of the tangential load displacement relationship on the degree of material dissimilarity.
Attempts at advancing the state of the art address the topic of material combinations and functionally graded materials.
For this intent, two sensor/coating systems are studied: a piezoelectric sensor coated with a functionally graded material, and a functionally graded piezoelectric sensor coated with a homogeneous material.
Three groups of lengths were investigated (i.e., 110, 60, and 30 mm), and four materials (i.e., titanium, flexible 'iso-elastic' material, and two functionally graded materials [FGMs]) were selected for each group.
The energy absorption of honeycombs made of a linear elastic-perfectly plastic material with constant and functionally graded density were estimated up to large crushing strains.
The crushing behaviour and energy absorption of honeycombs made of a linear elastic-perfectly plastic material with constant and functionally graded density were studied up to large crushing strains using finite element simulation.
During recent years, various ceramics, composites, cermets, and other materials, including Al, Ti, and functionally graded materials (FGM), have been successfully compacted by SPS [ 88– 96].
This paper proposes a hierarchical multi-scale topology optimization method for the design of integrated materials and structures by taking advantage of both cellular composites and functionally graded materials.
