Tresca Engenharia is one of the pioneering companies in Brazil specializing in the use of stress analysis using the finite element method to check the integrity of industrial equipment, increase the service life, study reinforcements and, in the manufacturing phase, optimize design with thickness, weight and material reductions (“design by analysis”).
USE
Any material or component can be analyzed, as long as its mechanical property (modulus of elasticity) is known. TRESCA already analyzed components made of steel and other metals, fiberglass reinforced plastic, polymers, rubber, cast iron and wood.
The method is applicable in calculation of stress, deformation, temperature distribution, thermal stress and vibration; dynamic response to random, seismic or harmonic excitation and plastic deformation by plasticity or creep.
In some cases, a non-linear analysis is made in order to study the deformation effect on the structure response and buckling analysis (elastic instability)
The stresses found are then compared, according to the case, with the allowable stresses, or the remaining life in fatigue or creep is calculated.
With the stresses found in the finite element analysis, a remaining life calculation or the limit operating condition of the component can be calculated. If the analysis is made during the design, is possible to optimize it, reducing its cost and increasing the operating capacity and remaining life.
If the product is moulded, it is possible to save on the mould cost and experimental samples. The analysis also replaces resistance and durability tests.
