Transient Thermal Conduction Example using Ansys

By -
Image
Introduction This tutorial was created using ANSYS 7.0 to solve a simple transient conduction problem. Special thanks to Jesse Arnold for the analytical solution shown at the end of the tutorial. The example is constrained as shown in the following figure. Thermal conductivity (k) of the material is 5 W/m*K and the block is assumed to be infinitely long. Also, the density of the material is 920 kg/m^3 and the specific heat capacity (c) is 2.040 kJ/kg*K. It is beneficial if the  Thermal-Conduction  tutorial is completed first to compare with this solution.

Contact Elements Using Ansys

Introduction This tutorial was completed using ANSYS 7.0 The purpose of the tutorial is to describe how to utilize contact elements to simulate how two beams react when they come into contact with each other. The beams, as shown below, are 100mm long, 10mm x 10mm in cross-section, have a Young's modulus of 200 GPa, and are rigidly constrained at the outer ends. A 10KN load is applied to the center of the upper, causing it to bend and contact the lower. Preprocessing: Defining the Problem Give example a Title Utility Menu > File > Change Title ... /title, Contact Elements Open preprocessor menu ANSYS Main Menu > Preprocessor /PREP7 Define Areas Preprocessor > Modeling > Create > Area > Rectangle > By 2 Corners BLC4,WP X, WP Y, Width, Height We are going to define 2 rectangles as described in the following table: Rectangle Variables (WP X,WP Y,Width,Height) 1 (0, 15, 100, 10) 2 (50, 0, 100, 10) Define the Type of Element Preprocessor > Element Type > Add...

Image
Introduction This tutorial is the last of three basic tutorials devised to illustrate commom features in ANSYS. Each tutorial builds upon techniques covered in previous tutorials, it is therefore essential that you complete the tutorials in order. The Solid Modelling Tutorial will introduce various techniques which can be used in ANSYS to create solid models. Filleting, extrusion/sweeping, copying, and working plane orientation will be covered in detail. Two Solid Models will be created within this tutorial. Problem Description A We will be creating a solid model of the pulley shown in the following figure. Geometry Generation We will create this model by first tracing out the cross section of the pulley and then sweeping this area about the y axis. Creation of Cross Sectional Area Create 3 Rectangles Main Menu > Preprocessor > (-Modeling-) Create > Rectangle > By 2 Corners BLC4, XCORNER, YCORNER, WIDTH, HEIGHT The geometry of the rectangles: Rectangle 1 Rectangle 2 Rectang...
