The methods utilized to compute engineering style and design values (A-foundation and B-basis) and acceptance sampling requirements had been developed independently while in the twentieth century. This was a useful approach for that time frame but it isn’t Functioning nicely for new resources with process dependent energy and modulus qualities, which include carbon fiber composite components.
