Composite Compressive Strength Modeller
User's Manual
1. Introduction
Welcome to the Composite Compressive Strength Modeller (CCSM) – a design tool for
deformation analysis and failure prediction of composite materials.
CCSM incorporates the following features:
1. Classical laminate theory for the prediction of laminate elastic properties;
2. Stress and strain analysis when in-plane forces and/or bending moments are applied;
3. Unnotched failure prediction by conventional failure criteria and the Budiansky-Fleck
compressive failure criterion;
4. Compressive failure prediction for notched composite plates.
5. A user-expandable database to store material and geometrical properties.
The program is a tool to predict laminate failure, once the loads on a section of the laminate are
known. For simple geometries it may be clear what the loading is, while for more complicated
geometries the program may be used as part of a larger calculation to check for failure at critical
points in the structure.
CCSM is written in Microsoft® Visual Basic TM language using Visual Studio 2012and it runs in
TM
operating system. It is structured so that the user, with a basic
the Microsoft® Windows
knowledge of composite mechanics, can use it with little reference to the manual. However, the
user would benefit from reading through this manual, in particular the Quickstart section, chapter
3 and the detailed guide, chapter 4. CCSM 2.0 updates and simplifies Version 1.4.
This manual consists of the following chapters:
1. Introduction.
2. Installation:
Instructions on how to install CCSM
3. Quick Start:
A 'quick start', self-sufficient chapter illustrating how to
use the CCSM package.
4. Detailed guide
Detailed guide to all aspects of the program with tutorials
