Abstract

Purpose

The purpose of this paper is to present the studies to develop structural highly orthotropic panels. These types of panels provide the capabilities required for structural morphing. They are highly deformable in one given direction; and in the perpendicular direction, one must be compliant to sustain the internal loads per certification stiffness and strength requirements.

Design/methodology/approach

Neither classic orthotropic panels nor regular cellular solids Bloch wave theories are strictly applicable on their study. A combination of computational method, MATLAB-coded, to analyze stability and classic structural beam theory is studied. Then, non-linear finite element method models are developed for an aerospace control surface application; their results are compared with reported Bloch wave sequences on periodic cellular solid panels.

Findings

The stability along stiffer direction is a requirement to obtain a continuous deformation and plasticization sequence of the cell rows in the perpendicular direction. A sample panel is sized and 3D modeled, and then produced using additive layer manufacturing process to demonstrate the initial stages of a validation and verification campaign.

Originality/value

This paper provides a new method to mechanical characterize highly orthotropic panels.

Abstract

This chapter's objective is to analyze, with a long-term perspective, the formation of an entrepreneurial culture in Mexico's Midwest, specifically in the state of Jalisco, in terms of the geographical environment, the culture in general, and the local economic institutions that, when viewed interconnectedly, will globally impact the practices, representations, and imaginaries of persons who at a given time have made the decision to undertake profitable economic activities – individual and collective entrepreneurs, in other words. To this end, we have divided the text into two sections. In the first, we conceptually review what we understand as entrepreneurial culture; in principle, we deconstruct its terms and then conjugate them from a social science perspective. We also emphasize the importance of studying the milieu as a scenario of action with different arenas, where a variety of agents have been involved. In the second part, without sidelining conceptual analysis, we present concrete empirical evidence of the role played by culture and local economic institutions that shape entrepreneurial culture in Midwestern Mexico over time, specifically in Jalisco. The text ends with some final considerations.
