modeling laminated glass response to extreme loading scenarios is a computationally demanding process in designing and analyzing protective structures. Therefore, an optimal modeling scheme requires a delicate tradeoff between accuracy and computational demand. This article investigates the failure modeling of laminated glass layups of thin and thick panels (three and 11 layers) under blast loading. This is done by implementing various simulation techniques: the finite element method with element erosion/deletion, the mesh-free method of smoothed particle hydrodynamics, and the hybrid implementation of mesh-based and mesh-free simulation through element conversions into particles. This Article examines the feasibility and limitations of each method, considering both the aspects of accuracy and computational cost in light of experimental testing results obtained from both arena and shock tube scenarios. mesh sensitivity and the significance of adaptive meshing in capturing the fracture patterns are evaluated. The present paper suggests that using hybrid techniques leads to optimal modeling results. Furthermore, the stability of the modeling results under diverse blast conditions is verified.

In modeling of elastic objects in a flow such as red blood cells, white blood cells, or tumor cells, several elastic moduli are involved. One of them is the area conservation modulus. In this paper, we focus on spring network models, and we introduce a new way of modeling the area preservation modulus. We take into account the current shape of the individual triangles and find the proportional allocation of area conservation forces, which would for individual triangles preserve their shapes. The analysis shows that this approach tends to regularize the triangulation. We demonstrate this effect on individual triangles as well as on the complete triangulations.

One of the most important characteristics of red blood cells is their elasticity and ability to return to original biconcave shape after external forces stop acting on them. There are several conservation laws that together govern this return and one of them is the area conservation. In this paper, we focus on local area conservation and introduce a new way of modeling it using a spring network model. We take into account the current shape of the network triangles and find the proportional allocation of area conservation forces, which would for individual triangles preserve their shapes. Since the force contributions in each node are combined from all adjacent triangles, the final resulting shape might not be the same, but overall effect on the triangulations is positive in the sense that this approach tends to regularize them.

This paper introduces SPACESKETCH, a new kind of sketch-basedmodeling system that can sketch free-form surface in space. This modeling system combines the advantages of a direct mesh-based sketch in which the user can draw the mesh directly in the space by moving the wand and the control curve sketch to express the detailed shape of the model. The created surface is also divided by using the control curve so that different resolution surfaces can be set for each surface and partially complicated parts can be sketched. While using SPACESKETCH, we introduced the advantages of using a new interface that uses mesh-based sketch and control curve sketch simultaneously to create various models and how to apply multi-resolution. Through this process, we show that mesh-based sketch and control curve sketch simultaneously to complement each other in a multi-resolution real time environment is very useful in concept sketching in a 3D environment using a spatial input device.
