Abstract: Some examples of National Severe Storms Project observations are described, showing certain typical structures of the mesoscale environment and of large thunderstorms in the Oklahoma-Texas-Kansas region. The ?dry-line? at ...

Abstract: In this paper, a new shape optimization approach, feature-based optimization of beam structures, is proposed to provide an efficient optimization solution of beam components in complex mechanical ...

Abstract: The stability characteristics of a milling system are investigated in this paper. A model is developed that includes the gyroscopic effects of the rotating spindle and on the basis of this ...

Abstract: We propose a method of evolving designs based on the user’s personal preferences. The method works through an interaction between the user and a computer system. The method’s objective is to ...

Abstract: A recently developed constitutive model and a finite element formulation for predicting the thermomechanical response of shape memory alloy hybrid composite (SMAHC) structures are briefly described. ...

Abstract: The effectiveness of a direct fire penetrator projectile equipped with an actively controlled ram air actuation mechanism is investigated through dynamic simulation. The ram air control mechanism ...

Abstract: Moisture poses a significant threat to the reliability of microelectronic assemblies and can be attributed as being the principal cause of many premature package failures. Of particular concern ...

Abstract: A new numerical model for the three-dimensional contact analysis of a layered elastic–perfectly plastic half space with another rough surface is presented. The model is based on a variational ...

Abstract: In Computer-Aided Design, when creating the solid model of a part, the designer knows how the part will interface with other parts, however this information is not stored with the part model. ...

Abstract: A three-dimensional transient thermoelastic solution is obtained for Rayleigh-type disturbances propagating on the surface of a half-space. These surface waves are generated by either a buried or ...
