Except as provided in paragraphs e and f of this section, compliance must be shown by selecting material design values which assure material strength with the following probability: What you will learn in this post: In this new regulation, more detailed guidance is included on the type of testing required to establish acceptable material properties. For more information on this topic, check out this link: Part a if this regulation combines two things, acceptable material specifications as well as tests required to establish the strength of materials and their properties. MMPDS is possibly the only document that is acceptable to the FAA for strength of materials and design allowable properties for most cases. Without it, certification with the FAA is possible, but it can get much more complicated and expensive. The strength of materials must be established on a statistical basis. For example, in MMPDS, all aluminum alloy materials need at least samples from 10 different lots and heats to produce the data that is required in statistical reduction. If you would like to learn more about the STAT17 tool used to perform statistical reduction, then check out this link: When tested as described in part a above, it is quite possible there is some variation among the different test results in the strength of materials.

It also covers the means of protection against such issues and the positive and negative side effects of these means of protection. For example, anodizing is used against corrosion of aluminum alloys, so read that post if you want to learn more.

In this regulation, the main topic is temperature. Temperature, either very hot or very cold, has the impact of either decreasing or slightly increasing the strength of materials respectively, if it is strictly based on an estimated temperature reduction factor TRF.

This chart shows the reduction in the ultimate tensile strength of Aluminum Alloy T plate, exposed to various elevated temperatures for up to 10, hours. The TRF is the read across value on the vertical axis for a temperature on the horizontal axis for a given exposure curve. The TRF is expressed as a percentage value compared to the room temperature strength. If you draw a vertical line from Deg.

F temperature may easily be exposed to such temperatures inside an engine nacelle, or maybe within a non-ventilated enclosure of the primary structure on a hot day in a desert airport for a few hours.

Mechanics and Strength of Materials

Hence, the room temperature ultimate tensile as well as shear, bearing and Young's modulus if separate curves are not available for each ultimate value strength of materials may be reduced by a factor of 0. This method or practice may vary from company to company, but the fact remains that the TRF must be accounted for.

Another important compliance factor is the thermally induced load which may also affect the induced load within various components. Or, there may be a unique assembly whose collective strength is tested for a one time use on a particular aircraft application.

In such cases, the component or assembly is tested using close to exact load and constraint conditions, to determine the superior strength. Of course, the use of safety factors is understood in margin calculations.
