“…Failure was predicted with Hou model [44] (Table 2). Hou approach, commonly used in composite mechanics, proposes the same formulation under tensile and compressive loading for fibre failure criterion, including longitudinal shear stresses r 12 and r 13 .…”

Cutting operations in bone are involved in surgical treatments in orthopaedics and traumatology.The importance of guaranteeing the absence of damage in the living workpiece is equivalent in this case to ensuring surface quality. The knowledge in this field is really far from the expertise in industrial cutting of mechanical components. Modeling of bone cutting is a challenge strongly dependent on the accurate modeling of mechanical behaviour of the bone. This paper focuses on modeling of orthogonal cutting of cortical bone. The intrinsic anisotropic nature of the cortical bone that makes it comparable to a compos-ite material is taken into account. The influence of anisotropy is analysed comparing this behaviour with an isotropic approach. It is shown that both chip morphology and temperature are affected by the anisot-ropy of the cortical bone that acts as a workpiece.

“…The material model used to describe the behaviour of woven glass/polyester laminates under ballistic impact derives from the Hou model [21], which was developed for carbon/epoxy tape laminates. Some modifications were required mainly due to the different reinforcement architecture.…”

“…An analytical model was used to estimate the ballistic limit and residual velocity in preloaded plates. In addition, a numerical model has been used, using the criterion of Hou et al [21] to predict the progressive failure of the panel. The results of the models were compared to those resulting from high-velocity impact tests on glass/polyester plain woven plates with a biaxial static preload, at velocities between 140 and 525 m/s.…”

In this work, the effect of a biaxial preload in the behaviour of glass/polyester woven laminate plates subjected to high velocity trans versal impact was studied. For this, an analytic model based on energy considerations that include the presence of an in plane preload was used. The results of the analytic model for the biaxial preload state were compared with those found for a non preload plate, the difference between them being minimal for the pre stressed level reached in the tests (31% of the static UTS). Therefore, numerical simulations were made in order to study the effect of the preload in greater detail; furthermore, experimental tests were conducted, validating the analytic and numerical model. In general, the two methods revealed minimal differences between the values of the ballistic limit and those of the residual velocity.

“…In the next decade the number of articles regarding high velocity impacts on carbon/epoxy laminates grew substantially, and not always the main focus was experimental, many of them had a numerical [16][17][18][19][20][21] or an analytical point of view [22][23][24][25][26], which is not the main porpoise of the current work.…”

In this work, the effect of high velocity impacts on carbon/epoxy tape quasiisotropic laminates is studied. Experimental test were carried out at two different impact angles and in a wide range of velocities (from 80 to 490 m/s). Both parameters, the residual velocity and the damaged area, are used to evaluate the effect of the kinetic energy of the projectile on the laminate response. In addition it has been proposed a simplified analytical model which allows to identify the different energy absorbtion mechanisms and predict the
