“…Surface damage area varied by 30 and 50% respectively for heating rate and strain rate dependent material properties [15]. More generally, studies have been conducted to experimentally determine the influence of strain on composite material properties [32,[34][35][36][37][38][39][40] however significantly less have focused on the combined effects of strain and heating rates [41,42]. Zhang et al [41] experimentally compared the effects of temperature and strain rate for 3D braided composites.…”

This paper proposes a progressive damage model incorporating strain and heating rate effects for the prediction of composite specimen damage resulting from simulated lightning strike test conditions. A mature and robust customised failure model has been developed. The method used a scaling factor approach and non-linear degradation models from published works to modify the material moduli, strength and stiffness properties to reflect the effects of combined strain and thermal loading. Hashin/Puck failure criteria was used prior to progressive damage modelling of the material. Each component of the method was benchmarked against appropriate literature. A three stage modelling framework was demonstrated where an initial plasma model predicts specimen surface loads (electrical, thermal, pressure); a coupled thermalelectric model predicts specimen temperature resulting from the electrical load; and a third, dynamic, coupled temperature-displacement, explicit model predicts the material state due to the thermal load, the resulting thermal-expansion and the lightning plasma applied pressure loading. Unprotected specimen damage results were presented for two SAE lightning test Waveforms (B & A); with the results illustrating how thermal and mechanical damage behaviour varied with waveform duration and peak current.

“…The final stage of benchmarking checked the heating rate and temperature boundary behaviour of the VUMAT. The experimental work of Pinto et al [42] was used to test temperature effects. Four DEN test cases were replicated using one 90 o and one 0 o ply with peak load predictions compared with the published experimental results.…”

“…To overcome the limitations of the CC test method, Catalanotti et al [15] proposed a static test method using double-edge notched (DEN) specimens and the relation between the size effect law and the 30 R-curve. In follow-up works, the method was extended to tensile [16] and shear loading [17] and recently used by Pinto et al [18] to measure the intralaminar crack resistance curves at extreme temperatures.…”

Composite Structures, 182,[164][165][166][167][168][169][170][171][172][173][174][175] This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. The results show that the steady state fracture toughness of the fiber compressive failure mode of the unidirectional carbon-epoxy composite material IM7-8552 is 165.6 kJ/m 2 and 101.6 kJ/m 2 under dynamic and quasi-static loading, respectively. Therefore the intralaminar fracture toughness in compression is found to increase with increasing strain rate.

In advance composite material the propagation of crack is a regular failure problem in various engineering applications especially in aircrafts body. The aircraft body components are subjected to various thermal and mechanical loading conditions. It is very difficult, time-consuming and costly process of testing the aircrafts components failure due to various thermal and mechanical conditions. Strain energy release rate (SERR) is the significant parameter for the composite materials and quality of composite materials depends on SERR values.The present investigation is based on ANSYS analysis for finding the strain energy release rate (SERR) value using Virtual Crack Closure Technique (VCCT) to understand the fracture behavior of the composite lamina. The circular crack present in the middle of the composite plate and subjected to pressure and temperature loading for different angle (cross-ply and angle-ply) composite structure laminas. The angle-ply shows less SERR in mode I & II while cross-ply shows less SERR in mode III under the constant pressure loading conditions. Mode II shows the maximum SERR in cross-ply compared to mode I and III for temperatures 30ºC, , 130 ºC and 180ºC. SERR for mixed-mode was found by considering the total mode of fracture and validation based on published literature for SERR due to the thermal load of mode I (GI) for different fiber layup configurations of the circular cut-out.
