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

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

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

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

ADVANCED TRENDS IN CAD/CAM
The term CAD/CAM is a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM). The term CAD/NC (Numerical Control) is equivalent in some industries.
CAD/CAM software uses CAD drawing tools to describe geometries used by the CAM portion of the program to define a tool path that will direct the motion of a machine tool to machine the exact shape that was drawn.
NUMERICALLY-CONTROLLED MACHINES
Well before the development of Computer-aided design, the manufacturing wor ....etc

INTRODUCTION
1.1 ABOUT THE TOPIC
Data Mining is the process of discovering new correlations, patterns, and trends by digging into (mining) large amounts of data stored in warehouses, using artificial intelligence, statistical and mathematical techniques. Data mining can also be defined as the process of extracting knowledge hidden from large volumes of raw data i.e. the nontrivial extraction of implicit, previo ....etc

Study and Modeling of the Mechanical Behavior of Hexagonal Metals

Introduction
Hexagonal close-packed (hcp) metals deform plastically by a variety of slip and twinning modes. The relative contribution of these mechanisms depends strongly on the material studied and the conditions, such as temperature, under which the deformation is performed. This work further elucidates the complicated competition and interactions between twinning and slip deformation modes for two hcp materials, namely zirconium and magnesium. The model presented here to ....etc

MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency of t ....etc
