Introduction

The Utah Laminates application is laminated plate theory software for the Macintosh. Utah Laminates was written by Prof. John A. Nairn from the Material Science and Engineering Department at the University of Utah. It is a shareware application. You can download a free demonstration copy from this web site. If you want to keep the software, you can register on line by clicking here. The shareware price is low and there is special pricing for students and faculty.

On this web site you can read a brief description of Utah Laminates, download Utah Laminates, and download a manual. This web site is divided into several sections. You can click on the links in the Site Index (on the left) to go to any section of the web site or simply scroll down to each section.

Downloading Options

The following download for Utah Laminates will give you a free demonstration copy. This copy has all the features of Utah Laminates except you are limited to analysis of eight ply laminates. The manual download provides a PDF version of the Utah Laminates manual. All information in the manual is included in the on-line help of the main Utah Laminates download.

Some Features of Utah Laminates

Here are some of the features of Utah Laminates. These and other features are documented in the on-line help or in the manual download above.

• Graphical editing of the laminate. You see a picture of each ply of the laminate; you can click to add or change plies, you can cut and paste plies to edit the laminate.
• Laminate analysis of all standard laminated plate theory matrices in either normalized or unnormalized form.
• Analysis of all engineering properties including couplings between flexural and in-plane strains and shear coupling constants
• Analysis of thermal expansion coefficients.
• Analysis of moisture expansion coefficients.
• You can subject a laminated to any combination of mixed stresses and strains, thermal loading, and moisture content and calculate all laminate and ply stresses and stress. Any component of the resulting stresses or strains can be plotted.
• Quick analysis of force-displacement law for various beam loadings for beams of any dimension made from a laminate.
• Plotting of plate displacements for any applied stress state.
• Each ply can be based or supplied ply properties or you can specify a fiber, matrix, and fiber volume fraction for the ply. When you specify fiber, matrix, and fiber volume fraction, the ply properties are calculated using state-of-the-art micromechanics based of variational mechanics solutions.
• All material properties can be edited and expanded to provide a data base of fibers, matrices, and plies to be available as building blocks for laminates.
• All calculation results are output to a standard Macintosh text-editing window. You can edit the text within Utah Laminates or you can copy the text to any word-processing software.
• The calculation output can be in user-selected units.
• All graphics results can be copied and pasted into any graphics editing software.
• All results can be printed.
• Complete on-line help is always available. The manual can be printed from within Utah Laminates or downloaded above as a PDF document.
