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.
Flexoelectricity is a size-dependent electromechanical mechanism coupling polarization and strain gradient. It exists in a wide variety of materials, and is most noticeable for nanoscale objects, where strain gradients are higher. Simulations are important to understand flexoelectricity because experiments at very small scales are difficult, and analytical solutions are scarce.
Hi everyone. I would like to know how to get started with a VUMAT subroutine for multiphases for example a subroutine for pore water and sand. It could be helpful when anyone could share VUMAT subroutines for learning such complex programmings. Could be appreciated when some one teaches with equations. thank you.
Hi I'm new in abaqus, I'm trying to make a coupled temp-displacement analysis with abaqus, but I cant fix an initial velocity in the predefined field in the inital step (I mean I can, but it doesn't work during the calculations), I already did the same thing with dynamic implicit analysis and it worked good
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.
Journal of Applied Mechanics (JAM) received 280 submitted manuscripts during the first 6 months in 2014. Among them only 4 are still in review.
The average time for the 1st round of review, with the decision to accept, or reject, or revise, is reduced to 10 days. For those that need revisions, the average time to make the final decision is 24 days after the 1st round of review, which include both the authors' revision time and 2nd (and more) round(s) of review.
