Determination of Composite Strength
Allowables With Reduced Testing

With

 Galib Abumeri
Alpha STAR Corp., Long Beach, CA


ABSTRACT

Determination of A- and B-Basis composite strength allowables solely by means of testing is costly and time consuming as large number of coupons must be tested under various environments. Alpha STAR Corp. developed a numerical approach to determine allowables with reduced number of test replicates. The capability identifies root cause for uncertainty in composite strength. It combines multi-physics/multi-scale progressive failure analysis with probabilistic methods to generate virtual test samples for use in predicting strength allowables. It has the potential of reducing test by more than 50% as compared to traditional practices. The speaker will describe the methodology in details and illustrate its effectiveness by presenting validation results for A- and B-Basis for several composite material systems subject to various environmental conditions (cold, ambient dry and elevated temperature dry and wet). Test reduction for material characterization will be central focus of the talk.

AlphaSTAR is a leading provider of engineering solutions for assessing Durability and Damage Tolerance (D&DT) of structures made from advanced materials (polymer, ceramics, nano, fiber metal laminates and honeycomb). The company services prominent aerospace industries and Government agencies.

BIO

Galib Abumeri, Technical Program Manager, AlphaSTAR Corp., Long Beach, CA. Mr. Abumeri specializes in composite micro-and-macro mechanics, durability and damage tolerance, reliability, and multi-disciplinary optimization. He devoted 16 years at NASA Glenn Research Center advancing computational modeling and simulation and assessing advanced technologies, with special focus on composites application. He received his B.S and M.S. in Mechanical Engineering from Cleveland State University, in Cleveland, Ohio (1988 and 1990). He authored more than 75 technical and journal papers and NASA reports in the areas of reliability of engine structures, composite D&DT, and material characterization. He serves as a member of the AIAA’s Non-Deterministic Approaches Technical Committee for structures and materials.
