The heat-seal strength and failure modes of laminated films with Linear Low Density Polyethylene (LLDPE) and Low Density Polyethylene (LDPE) as the sealant materials were investigated. Heat-seal strength increases with platen temperature for all samples. The maximum achievable heat-seal strength for laminated film using LDPE and LLDPE as sealant material is 0.598 N/mm and 4.02 N/mm, respectivel...

An ontology for representing operating, safety and control procedures is proposed in this paper that supports diagnosis based on following these procedures and combining observed malfunctions with Failure Mode and Effects Analysis (FMEA) information. The procedure ontology is defined within interconnected components of the process plant, diagnostic analysis (where the FMEA is described) and pro...

Background—The mode of death has been well characterized in patients with heart failure and a reduced ejection fraction; however, less is known about the mode of death in patients with heart failure and a preserved ejection fraction (HFPEF). The purpose of this study was to examine the mode of death in patients with HFPEF enrolled in the Irbesartan in Heart Failure With Preserved Ejection Fract...

A nonlinear elastic foundation model has been developed to predict the mixed-mode (modes I and II) delamination failure of laminated composites. Two types of nonlinear elastic foundations were used to represent pure mode I and pure mode II components of the material failure ahead of the crack tip. One is a tension spring foundation for mode I component and the other is a shear spring foundation...

this paper aims at investigating the effects of weld nugget size and expulsion on the mechanical properties of low carbon steel resistance spot welds using tensile-shear test. mechanical performance of spot welds are described in terms of failure mode, peak load and failure energy obtained from the tensile-shear test. the effects of voids and porosity as well as electrode indentation associated...

Introduction: To evaluate and compare shear bond strength of self-cure and  light-cure composites using a universal bonding system. Materials and Methods: Superficial coronal dentin of 62 intact extracted  premolars was exposed and bonding agent (All-Bond Universal) was applied over the  dentin surface according to the manufacturer instruction (self-etch mode). Then  samples were distribut...

Failure mode and effects analysis (FMEA) is awidely used engineering technique for designing, identifying and eliminating theknown and/or potential failures, problems, and errors and so on from system to other parts. The evaluating of FMEA parameters is challenging point because it’s importantfor managers to know the real risk in their systems. In this study,we used fuzzy TODIM for evaluating t...

A mechanical model for the prediction of mode I delamination failure of a laminated double cantilever beam (DCB) type specimen is presented. The volume of material ahead of the crack tip that experiences high stresses due to the presence of the crack tip was replaced by a nonlinear elastic spring foundation. The volume undergoing global deformation due to the external loading was replaced by a ...
