“…The most popular software packages used to analyze the impact behavior of composite materials are ABAQUS, ANSYS, and NASTRAN. Many professional computer aided design‐based engineering software companies such as COSMOL, Creo Parametric and SOLIDWORKS have also recognized the importance of finite element analysis (FEA) and have included or will include FEA modules in their future versions so that engineers and scientists working in academic or industrial sectors worldwide prefer these software in their work 7 . A large number of experimental and numerical studies have been performed to determine the low‐velocity impact behavior of thick laminated composite materials 8–10 .…”

In this study, the dynamic behavior under low‐veloctiy impact of E‐glass epoxy unidirectional thick laminated composite structure was investigated by numerical methods and compared with experimental results. Thereby, it was aimed to detect the impact behavior of the composite structures with numerical analysis program for reducing experimental tests on these composite structures. LS‐DYNA finite element method (FEM) software was used for numerical modeling. The material model MAT055, which is based on the Tsai–Wu matrix failure modeling on damage mechanics, was selected for the analyses in LS‐DYNA. Low‐velocity impact analyses have been carried out on composite structures at various impact energies as a range of 15–250 J as similar to experiments. From the analysis of the plots, it can be seen that the values of absorption energy provided by the FEM analyses are close to the experimental values at all impact energy levels. It can be determined that the mean difference between the absorption energy levels provided from the experimental and numerical studies is 1.81%. In the same studies, matrix cracking was observed at 50 J impact energy value and full penetration was observed at 250 J impact energy. The error rate between the values obtained using the derived impact energy prediction equation and the values obtained as a result of numerical analysis was maximum 5.26%. Thus, derived equation was found to be reasonable for use in predicting the absorption energy. As a result, these values indicate that the experimental results are agreed well with the numerical results.Highlights Dynamic behavior under impact of thick laminated composite was investigated. Impact analyses were performed at impact energies as a range of 15–250 J. At 250 J impact energy, the composite deformed with full penetration damage. Impact damage areas were calculated according to impact energy levels. It would be useful to use numerical analysis method in terms of cost and time.

“…From the engineering perspective, it is detrimental to analyse the behaviour of a component when it starts corroding in service [10]. Numerical modelling provides an efficient and effective manner to study how the stress distribution and concentration in a component will vary once it corrodes by introducing the corroded morphology in the specimen or component using computer-aided design (CAD) [11][12][13]. The CAD model is subjected to the desired loading conditions in terms of clamping and pressures.…”

The paper describes the corrosion based degradation of aluminium alloys using an analytical and numerical framework. The corrosion rate was calculated using analytical equations for aluminium sheets subjected to a corrodent. Parametric analysis for the pit morphology, diameter, depth and distribution on the plate was conducted using finite element analysis. A comparison between elliptical and circular pits of the same area was also made for stress magnification using numerical analysis. It was observed that the stress generated at constant load when a specimen corrodes due to pitting is directly proportional to the pit diameter and pit depth. Zigzag pit morphologies due to the combined effect of mechanical degradation and corrosion have the highest stress at the corners of the pattern, while circular pits have the highest stress at the centre of the pit. The zigzag pit morphology has more detrimental effects than circular pits. For multiple distributed pits, the pits closer to the specimen edges exhibit higher stress values than those near the centre of the specimen. The effect of multiple or quantitatively increased number of pits having smaller geometric properties has a more detrimental effect than a single pit with larger geometric attributes.
