    Abstract: An analysis accuracy evaluation method includes: generating, based on measurement data obtained by measurement of a shape after die release of an actual press-formed part press-formed with a predetermined tool of press forming by utilization of an actual blank taken from a metal sheet having shape variation; generating an actual blank model having a same shape as the actual blank based on measurement data; acquiring a press-formed part shape after die release as an analysis press-formed part shape by performing, by using the actual blank model, a press-forming analysis of when press forming is performed with a model of a tool of press forming which model has a same shape as the predetermined tool of press forming; and comparing the actual press-formed part shape and the analysis press-formed part shape, obtaining a deviation amount of shape change of the both shapes, and evaluating accuracy of the press-forming analysis.

    Abstract: One example includes a method for validating a circuit design. The method includes providing a set of coded rules. Each of the coded rules can define conditions for circuit cells to qualify the circuit design as being radiation-hardened. The method also includes accessing a circuit design netlist associated with the circuit design from a circuit design database. The method also includes evaluating each of the circuit cells in the circuit design netlist with respect to each of the coded rules. The method further includes providing a circuit evaluation report comprising an indication of failure of a set of the circuit cells with respect to one or more of the coded rules in response to the evaluation.

    Abstract: A method of evaluating a stress applied to components of a switchgear cabinet for sustaining an arc-flash with an arc-flash event simulation and energy transmission thereof is presented with steps comprising providing a location of the arc-flash in an internal volume of the switchgear cabinet, simulating the arc-flash as a local ambient boundary condition at the location of the arc flash with an input energy, diffusing the input energy in an air domain inside the switchgear cabinet, applying the input energy as a thermal history to specific arc-flash elements, multiplying the thermal history by specific heat to calculate energy units at the arc-flash, identifying a desired thermal energy magnitude and history of deposition and calibrating the desired thermal history to substantially match an estimated mechanical power generated by the arc-flash.
