Numerical Simulation of Cropping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cropping is a cutting process whereby opposing aligned blades create a shearing failure by exerting opposing forces normal to the surfaces of a metal sheet or plate. Building on recent efforts to quantify cropping, this ...
Nonlinear Buckling Interaction for Spherical Shells Subject to Pressure and Probing Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastic spherical shells loaded under uniform pressure are subject to equal and opposite compressive probing forces at their poles to trigger and explore buckling. When the shells support external pressure, buckling is ...
Door Latch Failure Risk Identification Using Virtual Testing Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vehicle door latch performance testing presently utilizes uniaxial quasi-static loading conditions. Current technology enables sophisticated virtual testing of a broad range of systems. Door latch failures have been observed ...
The Path-Independent M Integral Implies the Creep Closure of Englacial and Subglacial Channels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drainage channels are essential components of englacial and subglacial hydrologic systems. Here, we use the M integral, a path-independent integral of the equations of continuum mechanics for a class of media, to unify ...
Rolling at Small Scales
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rolling process is widely used in the metal forming industry and has been so for many years. However, the process has attracted renewed interest as it recently has been adapted to very small scales where conventional ...
Buckling Thresholds for Pre-Loaded Spherical Shells Subject to Localized Blasts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the robustness against localized impacts of elastic spherical shells pre-loaded under uniform external pressure. We subjected a pre-loaded spherical shell that is clamped at its equator to axisymmetric ...
The Geometric Role of Precisely Engineered Imperfections on the Critical Buckling Load of Spherical Elastic Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study the effect of a dimplelike geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling, and ...
Technical Brief: Knockdown Factor for the Buckling of Spherical Shells Containing Large-Amplitude Geometric Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We explore the effect of precisely defined geometric imperfections on the buckling load of spherical shells under external pressure loading, using finite-element analysis that was previously validated through precision ...
