“…A powerful exploitation of tomographic approaches is threedimensional digital volume correlation [334,335] where microscale changes are characterized over the loading history. Micro-scale in situ validation using tomographic approaches have been investigated for cellular materials (both metallic and polymeric) [330,331,336], metals [337], and woven composites [338,339], just to name a few. Such image-based multiscale validation techniques with co-designed simulations will provide further confidence in physics simulation codes and advance the ICME paradigm (see Section 1).…”

Since the beginning of the industrial age, material performance and design have been in the midst of innovation of many disruptive technologies. Today's electronics, space, medical, transportation, and other industries are enriched by development, design and deployment of composite, heterogeneous and multifunctional materials. As a result, materials innovation is now considerably outpaced by other aspects from component design to product cycle. In this article, we review predictive nonlinear theories for multiscale modeling of heterogeneous materials. Deeper attention is given to multiscale modeling in space and to computational homogenization in addressing challenging materials science questions. Moreover, we discuss a state-of-the-art platform in predictive image-based, multiscale modeling with co-designed simulations and experiments that executes on the world's largest supercomputers. Such a modeling framework consists of experimental tools, computational methods, and digital data strategies. Once fully completed, this collaborative and interdisciplinary framework can be the basis of Virtual Materials Testing standards and aids in the development of new material formulations. Moreover, it will decrease the time to market of innovative products.

“…Fiber failures can also be modeled by cohesive elements. In a series of articles, Bouvet et al [199,[232][233][234] use cohesive elements to High velocity impact [201,275,372,373] Soft impact [202,[254][255][256] Crushing tube [203,326] Crushing plate [349,350] Energy absorbing structures [338,339,374] predict both intraply and interlaminar damage during low velocity impacts. This approach was also used to study the compression after impact behavior of laminates [235].…”

This article surveys existing cohesive zone models (CZM) and their use in numerical simulations for analysis impacts on composite structures and predicting the damage induced. These models are used for matrix cracks and delamination. The first part of article gives the required background on failure criteria for predicting the onset of delaminations, on fracture mechanics and the various types of CZM. The second part discusses applications of CZM to several types of impact problems with composite structures. Applications for these models to other problems are briefly mentioned at the end. CZM are now part of state of the art numerical simulations with progressive damage analysis.

“…which can typically highlight delamination damage, generally with no real distinction of other types [25,29,30]. The second is X-ray computed tomography (CT), which provides full volumetric analysis revealing damage modes such as delamination and other main energy-dissipating intra ply mechanisms [31][32][33][34]. The volumes reconstructed with CT can be analysed to define many other typical impact features such as cone cracking [5,10].…”

With extensive use of composite materials in aerospace, marine, energy and defence applications, their susceptibility to impact events is still an unresolved problem. In this paper, impacts of carbon fibre/epoxy composite specimens with solid (steel) and fragmenting (ice) spherical projectiles are studied extensively, using a combination of non-invasive analysis techniques to assess their dynamic deformation behaviour and resultant damage. The velocity magnitudes of highintensity impacts varied between 70 and 90 m/s for solid projectiles and between 300 and 500 m/s for fragmenting ones, resulting in three consistent and comparable levels of structural damage for both cases. A new in-depth deformation analysis method based on high-speed digital image correlation was utilised to assess the effect of both the projectile type and impact velocity, resulting in a deeper understanding of the specimen's deformation behaviour allowing detailed observation of its stages during the impact event. Additionally, both visual and non-invasive methods were employed to analyse the extent of damage related to various dynamic loading conditions. X-ray computed tomography was used to implement a full volumetric analysis of internal damage and resulted in a detailed insight into inter-and intra-ply damage modes.
