“…Figure 16a and b show the comparison of CFE between numerical simulation and experiment tests. In contrast with metal specimen [31], composite structure shows near ideal progressive failure when P ave is close to P max . The effect of geometry can be seen as the dominant effect on CFE crashworthiness indicator.…”

“…To demonstrate the damage initiation and progressive failure, Hashin's criteria was applied in ABAQUS where the onset of damage is related to material degradation. Hashin's failure prediction is evaluated by four different criteria, namely, fiber failure in tension, matrix failure in tension, fiber failure in compression and matrix failure in compression [31]. When all these criteria are not reached, the structure is safe but when one or more of these equations are satisfied, damage is initiated.…”

“…For the FF mode, the stress components on the fracture plane are τ 12 , τ 13 and σ 1 [8]. However, the contribution of the shear stress components τ 12 and τ 13 to fiber fracture is very small, and hence can be neglected [32]. Therefore, the equivalent stress and strain for the FF mode are defined as:σeq,FF=σ12, εeq,FF=ε12.…”

“…Hashin hasar kriteri deneysel sonuçlarla uyumlu bir şekilde kullanılmaktadır. Ayrıca bu kriterin farklı kriterlerle karşılaştırması yapılmakta (Duarte vd., 2017) ve modifikasyonları geliştirilmektedir (Gu ve Chen, 2017 (Turan vd., 2015;Turan ve Orcen, 2017). Bu çalışmada ise, çekme yükü etkisindeki ortasında dairesel delik bulunan kompozit levhada sayısal nihai hasar değeri, çekme testlerinde olduğu gibi kırılma sonucu maksimum reaksiyon kuvvetinin düşmeye başladığı nokta kontrol edilerek belirlenmiştir.…”
