Aiming at the prefabricated composite structure, a new type of interior joint in the prefabricated slab wall system suitable for light steel-concrete composite structures is proposed. In the paper, the pseudo-static test of the joint was designed and carried out, and its failure pattern was mainly described. In addition, the test data was analysed from the perspectives of load-displacement curve, strength, stiffness, ductility and energy dissipation. The finite element analysis software ABAQUS was used to carry out finite element modelling and calculation of the new joint, and the results were compared and analysed in terms of failure process and load-displacement curve analysis. The results show that it is feasible to apply the joints in this new type of slab wall system to light steel concrete composite structures.

A general method for integrating genetic algorithms within a commercially available finite element (FE) package to solve a range of structural inverse problems is presented. The described method exploits a user-programmable interface to control the genetic algorithm from within the FE package. This general approach is presented with specific reference to three illustrative system identification problems. In two of these the aim is to deduce the damaged state of composite structures from a known physical response to a given static loading. In the third the manufactured lay-up of a composite component is designed using the proposed methodology.

Determination of transverse mechanical properties from the ring type of specimens directly machined from the nuclear reactor pressure tubes is not straightforward. It is due to the presence of combined membrane as well as bending stresses arising in the loaded condition because of the curvature of the specimen. These tubes are manufactured through a complicated process of pilgering and heat treatment and hence, the transverse properties need to be determined in the as-manufactured condition. It may not also be possible to machine small miniaturized specimen in the circumferential direction especially in the irradiated condition. In this work, we have performed ring-tensile tests on the un-irradiated ring tensile specimen using two split semi-cylindrical mandrels as the loading device. A three-dimensional finite element analysis was performed in order to determine the material true stress–strain curve by comparing experimental load–displacement data with those predicted by finite element analysis. In order to validate the methodology, miniaturized tensile specimens were machined from these tubes and tested. It was observed that the stress–strain data as obtained from ring tensile specimen could describe the load–displacement curve of the miniaturized flat tensile specimen very well. However, it was noted that the engineering stress–strain as directly obtained from the experimental load–displacement curves of the ring tensile tests were very different from that of the miniaturized specimen. This important aspect has been resolved in this work through the use of an innovative type of 3-piece loading mandrel.

The bioengineering and medical and biomedical fields are ever closer, and they manage to obtain surprising results for the development of new devices. The field of simulations and studies in silica has undergone considerable development in recent years, favoring the advancement of medicine. In this manuscript, a study was carried out to evaluate the force distribution on the implant components (In-Kone® Universal) and on the peri-implant tissues subjected to loading. With the finite element analysis and the Von Mises method, it was possible to evaluate this distribution of forces both at 0 degrees (occlusal force) and at 30 degrees; the applied force was 800 N. The obtained results on this new type of connection and on all the implant components are satisfactory; the distribution of forces appears optimal even on the peri-implant tissues. Surely, studies like this help to obtain ever more performing devices, improving both the clinic and the predictability of rehabilitations.

Rubber-sleeved headed stud shear connector is flexible shear connector used in steel-concrete composite structures. In this work, nonlinear finite element model has been developed to simulate the failure process of the shear connector under shear loading. The stress distribution, deformation, crack propagation and failure mode were analyzed. The material nonlinearities of rubber, headed stud, concrete were considered in the material model. The rubber was assumed as a perfect material with no defect, and a modified reduced polynomial form of strain energy including an energy limiter and a new constant was introduced into the user material subroutine VUANISOHYPER-INV of ABAQUS software. Damaged plasticity model was used to model the concrete material. A tri-linear elastic-plastic curve was used in stud material model. Comparing the results obtained from the finite element analysis with those from push-out test, good agreement is highlighted in the capacity, ductility and failure mode of rubber-sleeved headed stud shear connector.

The Finite Element Analysis

Being corrosion resistant, light weight, and easy to install at relatively low cost, Reinforced Thermoplastic Pipe (RTP) is now increasingly being used for offshore operations. RTP pipe in this study is mainly composed of three layers: a wound high strength fiber reinforced layer to improve the resistance of the pipe to internal pressure; a plastic inner layer to transport fluid; a plastic outer layer to protect the pipe. A precise calculation of the burst strength of RTP pipe will be useful for the safe use of RTP pipe’s internal pressure resistance. The Finite Element Analysis (FEA) method and mathematical analysis are employed to study the properties of pipe under internal pressure. The Finite Element Analysis method is used to simulating the pipe under increasing internal pressure using ABAQUS. The model is established with the conventional shell element, and the anisotropic property of plastic is also considered in the model. In the mathematical analysis, the reinforcement layer of the pipe is assumed to be anisotropic and other layers are assumed to be isotropic. Based on the three-dimensional (3D) anisotropic elasticity theory, an exact elastic solution for burst strength of the pipe under internal pressure has been studied. This paper focus on the calculation of RTP pipe’s burst strength, using mathematical approach and FEA approach, on the basis of elaborated study of RTP pipe’s failure process. Our results from mathematical and FE simulation agree each other for burst pressure of the RTP pipe. Our FEA models are also compared with the experimental research in order to validate our FEA models.
