Fluid mechanics is the branch of physics that studies the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics has a wide range of applications, including for mechanical engineering, chemical engineering, geophysics, astrophysics, and biology. Fluid mechanics can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out ....etc

I am trying to model prestress in Hollow Concrete Slabs in Abaqus CAE in 3D. I have set up the model with rebars (truss elements) embedded in the concrete slab (Brick elements).

However there is no CAE usage for prestress which means that presumably, the prestress can only be introduced in the generated script (the journal file .jnl).

Although the manuals indicate how prestress can be introduced ( Initial Conditions' and Prestress Hold'), the problem is that I have no experience with scripting or using python programming.

Would using ....etc

Can anyone please help with the Piezoelectric actuator modelling in ABAQUS?

1) I am going to measure the mechanical displacements caused by the electrical load (constant electrical voltage) in a cantilever laminate with incorporated piezoelectric actuator patches polarized through thickness (Z direction). I considered the laminate is thin, taking into account the plane stress rather than the plane strain. I assigned shell section to both laminate and piezoelectric patches in ABAQUS section assignment. Considering through-thickness polarizat ....etc

Introduction to Fluid Mechanics

.Fluid Mechanics is concerned with the behavior of fluids at rest and in motion

.Distinction between solids and fluids:
-According to our experience: A solid is hard and not easily deformed. A fluid is soft and deforms easily.
-Fluid is a substance that alters its shape in response to any force however small, that tends to flow or to conform to the outline of its container, and that includes gases and liquids and mixtures ....etc

Electrorheological fluids are suspensions of extremely fine non-conducting particles (up to 50 micrometres diameter) in an electrically insulating fluid. The apparent viscosity of these fluids changes reversibly by an order of up to 100,000 in response to an electric field. For example, a typical ER fluid can go from the consistency of a liquid to that of a gel, and back, with response times on the order of milliseconds. The effect is sometimes called the Winslow effect

The ER effect

The change in apparent viscosity is dependent on the ap ....etc

Reactive Powder Concrete (RPC) is a developing composite material that will allow the concrete industry to optimize material use, generate economic benefits, and build structures that are strong, durable, and sensitive to environment. A comparison of the physical, mechanical, and durability properties of RPC and HPC (High Performance Concrete) shows that RPC possesses better strength (both compressive and flexural) and lower permeability compared to HPC. This page reviews the available literature on RPC, and also presents the results of laborat ....etc

Material flow in friction stir welding (FSW) under different process parameters is simulated by using the finite element technique based on the nonlinear continuum mechanics. Results indicate that the distribution of the equivalent plastic strain correlates well with the distribution of the microstructure zones in the weld. It seems that there is a quasi-linear relation between the change of the axial load on the shoulder and the variation of the equivalent plastic strain. The material flow can be accelerated with the increase of the translatio ....etc
