Thermo-hydro-mechanics (THM) is a branch of mechanics aimed to predict how deformable porous media behave, while heat transfer and fluid transport simultaneously occur in the pores filled by liquid and/or gas. Understanding these multi-physical responses is important for a wide spectrum of modern engineering applications, such as tissue scaffolding, geothermal heating, mineral exploration and mining, hydraulic fracture, energy piles, tunneling with frozen soil and nuclear waste storage and management.
Hybrid and hierarchical polymer composites represent a promising group of materials for engineering applications. In this paper, computational studies of the strength and damage resistance of hybrid and hierarchical composites are reviewed. The reserves of the composite improvement are explored by using computational micromechanical models. It is shown that while glass/carbon fibers hybrid composites
3D computational model of graphene reinforced polymer composites is developed and applied to the analysis of damage and fracture mechanisms in the composites. The graphene/polymer interface properties are determined using the inverse modeling approach. The effect of composite structure, in particular, of the aspect ratio, shape, clustering, orientation and volume fraction of graphene platelets on the mechanical behavior and damage mechanisms of nanocomposites are studied in computational experiments.
We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.

Sleek and modern elegance is offered with a titanium ring Cartier watches replica. it's always possible to find a titanium ring that is perfect for your unique style and taste. pieces should not be too thin. there will be a sales person to handle your purchase. and you might have to be thankful as this particular gemstone brings protection when there is darkness or when you are having nightmares. life and strength.
I want to use Calculix explicit for large deformation problem. I want to use a user subroutine similar to vuhard (in ABAQUS) to model the material behaviour. Calculix documentation metions uhardening, but there is nothing similiar to vuhard.
Complex structures consisting of intertwined, nominally vertical carbon nanotubes (CNTs) are called turfs. Under uniform compression experiments, CNT turfs exhibit irreversible collective buckling of a layer preceded by reorientation of CNT segments. Experimentally observed independence of the buckling stress and the buckling wavelength on the turf width suggests the existence of an intrinsic material length.
I test the proficiency of SPH method dealing with a benchmark numerical example solving Poisson's equation; SPH shows the good efficiency in modeling the contours, but the value of results change for a di
This paper investigates what is the largest magnetoelectric (ME) coefficient of ME composites, and how to realize it. From the standpoint of energy conservation, a theoretical analysis is carried out on an imaginary lever structure consisting of a magnetostrictive phase, a piezoelectric phase, and a rigid lever. This structure is a generalization of various composite layouts for optimization on ME effect.
Bamboo, as a natural hierarchical cellular material, exhibits remarkable mechanical properties including excellent flexibility and fracture toughness. As far as bamboo as a functionally graded bio-composite is concerned, the interactions of different constituents (bamboo fibers; parenchyma cells; and vessels.) alongside their corresponding interfacial areas with a developed crack should be of high significance.
Hello ANSYS masters, I am student of M.Tech and I am currently doing my dissertation on Friction stir welding stimulation using ANSYS Mechnical APDL. The problem I face is in defining the time substep in the load step defined as follows
I am trying to study the fracture at bonded interfaces using cohesive zone model in Abaqus. I am going through the abaqus manual but it was not clear how to insert the chosive elements in the model. How to model these chosive elements. Can anyone help in modelling the chosive elements.
