A critical evaluation of dynamic fracture simulations

Abstract. Finite element calculations of dynamic fracture based on embedding cohesive surfaces in a continuum indicate that the predictions are sensitive to the cohesive law used. Simulations were performed on a square block in plane strain with an initial edge crack loaded at a constant rate of strain. Cohesive laws that have an initial elastic Accuracy of concrete strength prediction behavior in This study investigates the accuracy of prediction normal concrete behavior in simulating punching shear strength of flat slab using finite element modelling in Abaqus.

Failure Modelling of Trabecular Bone Using a Non-Linear Combined Damage and Fracture Voxel Finite Element Approach The Dependence of Shear Failure Properties of Trabecular Bone An investigation of the block shear strength of coped their final failure mode. No shear fracture was observed in all of the tests. A comparison between the ultimate loads in the test and the predictions using the current design equations indicates that the current design standards such as the AISC-LRFD, CSA-S16-01, Eurocode 3, BS5950-1:2000, AIJ and GB50017, are inconsistent in

Assessment Of Fatigue And Fracture Strength Of

The flywheel's strength was estimated using a detailed 3-D finite element (FE) simulation incorporating contact surfaces and sub-modelling techniques. Critical areas were identified near the bolt's holes and, although the simulated strength was considered safe under normal operation (about 3000 RPM), it was conceived that failure due to Assessment of fatigue and fracture strength of Assessment of fatigue and fracture strength of transportation energy storage flywheel using finite element simulation L, Wang, X,J. Ren & G, Shatil This radial deformation difference leads to shear load on the bolts in the interface between the parts and slight bolt deformation.

Damage propagation and strength prediction of a single-lap

Experimental and finite element research was conducted on the bolted interference fit of a single-lap laminated structure to reveal the damage propagation mechanism and strength change law. A typical single-lap statically loading experiment was performed, and a finite element damage prediction model was built based on intralaminar progress Development of Layout Factor for Mechanical Shear Shear joints having 2, 3, 4, 6 and 8 bolts are considered in the analysis. Different layouts are shown in the Fig. 2. The dimension of the plate increases with the increase in the number of bolts. Same bolt size (M16) is used in all layouts. The dimension of the plate increases with the increase in the number of bolts.

Finite Element Single-Bolt Shear Connection Shear-Out

Apr 09, 2018 · Abstract. The finite element (FE) predictions of single-bolt connections shear-out failure in the literature were conducted with only elasticplastic material models without any fracture model. This paper presents the FE single-bolt connection shear-out fracture (SBCSOF) prediction and failure analysis using the phenomenological shear fracture model. International Journal of Engineering Research & one connection failed by bolt fracture, weld fracture, or plate shear fraction. The experimental results led to concerns for bolt prying forces and end-plate shear forces. Finite element analysis was used to predict the bolt forces and to predict the magnitude and location of the prying forces. Sumner [4] investigated the performance of
