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

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.

Application of Joints and Springs in ANSYS

Introduction This tutorial was created using ANSYS 5.7.1. This tutorial will introduce: the use of multiple elements in ANSYS elements COMBIN7 (Joints) and COMBIN14 (Springs) obtaining/storing scalar information and store them as parameters. A 1000N vertical load will be applied to a catapult as shown in the figure below. The catapult is built from steel tubing with an outer diameter of 40 mm, a wall thickness of 10, and a modulus of elasticity of 200GPa. The springs have a stiffness of 5 N/mm. Preprocessing: Defining the Problem Open preprocessor menu /PREP7 Give example a Title Utility Menu > File > Change Title ... /title,Catapult Define Element Types For this problem, 3 types of elements are used: PIPE16, COMBIN7 (Revolute Joint), COMBIN14 (Spring-Damper) . It is therefore required that the types of elements are defined prior to creating the elements. This element has 6 degrees of freedom (translation along the X, Y and Z axis, and rotation about the X,Y and Z axis). Define P
