“…However, the MCT prediction of the failure envelope shows that the tensile strength is reduced slightly with increasing composite stresses in 2 and 3 directions. This phenomenon is due entirely to the MCT decomposition and is demonstrated by the fiber stress state shown in equation (14) (repeated below for convenience) which is the result of a biaxial compressive stress of 22 …”

“…As a result, the biaxial (s xx À s yy ) behavior predicted by Mayes and Hansen in Figure 3 is more typical of carbon/epoxy materials. 14 A second shortcoming of the MCT analysis of Mayes and Hansen relates to the incorporation of nonlinear shear effects. Nonlinear shear prior to macroscopic crack formation may be attributed to damage caused by submicrocrack accumulation in the matrix material.…”

Triaxial failure analysis using multicontinuum decomposition has been employed at the constituent level to predict nonlinear damage behavior and failure envelopes, all involving through-thickness stresses. In addition, a structural analysis algorithm is presented and is found to be numerically highly efficient in that the relationships between composite properties and damaged or failed constituent properties are completely determined prior to structural analysis. As a part of the Second World-Wide Failure Exercise, three-dimensional failure envelopes and stress-strain curves involving isotropic materials as well various unidirectional and multi-directional materials are presented for 12 test cases requested by the organizers. The present paper provides new developments in the multicontinuum methodology including: (a) modification of the constituent failure criteria, (b) incorporation of pressure effects, (c) new damage analyses, and (d) implementation into a commercial finite element package. Correlation with experimental results is provided in a second article addressing Part B of the Second World-Wide Failure Exercise.
