Abstract
JAXA contributes to the SIP (Cross-ministerial Strategic Innovation Promotion) program, which is governed by Cabinet Office, Government of Japan. JAXA takes charge high fidelity modeling of the polymer matrix composites for aircraft structure. The calculation for the modeling is performed in this topic.

Use of the Supercomputer
Supercomputer was used for the explicit finite element damage simulation of the open hole tensile (OHT) test against CFRP laminate.
Necessity of the Supercomputer
Huge number of elements are needed for detailed damage simulation in CFRP. Application of the supercomputer system makes such high-computational-cost calculation possible.
Achievements of the Year
Damage simulation of CFRP under open-hole tensile (OHT) test was performed using ECDM (Enhanced Continuum Damage Mechanics) model, which was damage model developed in JAXA.
Simulation was performed using ABAQUS/Explicit 2016 on JSS2 system. Each ply of the CFRP laminate was modeled by one continuum shell element in the thickness direction. ECDM model was implemented using usersubroutine of ABAQUS.
Figure 1 shows model overview, and Figure 2 shows the predicted damage. Damage area and strength will be compared to the test results.
