I was unable to get the equations with specific symbols to appear correctly.

The code is like this

bm{sigma}(t)=bm{sigma}^{vol}+bm{sigma}^{dev}(t)=Ktext{tr}

({bm{varepsilon}})bm{I}+2int_{0}^{t}G(t-tau)dot{bm{e}}(tau)dtau,

What I expected was to get a pdf like this

However, the pdf seems to hate me...

Could anybody help me resolve this issue?

Here I post the minimal part of the compiled text that works,

documentclass[Journal,letterpaper]{ascelike-new}

usepackage[utf8]{inputenc}

usepackage[T1]{fontenc}usepackage{lmodern}usepackage{graphicx}

usepackage[figurename=Fig.,labelfont=bf,labelsep=period]{caption}

usepackage{subcaption}

usepackage{newtxtext,newtxmath}

usepackage[colorlinks=true,citecolor=red,linkcolor=black]{hyperref}

usepackage{bm}

usepackage{soul}

usepackage{tikz}

usepackage{ulem}

usepackage{color}

usepackage{cancel}

usepackage{dsfont}

usepackage{amssymb}

usepackage{textcomp}

usepackage{setspace}

usepackage{pgfplots}

pgfplotsset{compat=1.14}

usepackage{fancyhdr} % Needed to define custom headers/footers

setlength{headheight}{15pt}

begin{document}

begin{equation}

bm{sigma}(t) = bm{sigma}^{vol} + bm{sigma}^{dev}(t)  = K text{tr} 

   ({bm{varepsilon}})bm{I}+2int_{0}^{t}G(t-tau)dot{bm{e}}(tau)dtau,

end{equation}

end{document}`

Best,

The offending packages seem to be the combination of mathptmx and newtxmath here (or more generally loading another font after newtxmath). As Yorgos already mentioned you load quite a few competing font packages and you might want to simplify things by removing the ones you don't really need (for example newtxmath and newtxtext would overwrite most of lmodern's effects). The following slimmed down preamble should work (I also removed some packages which were loaded twice):

documentclass[Journal,letterpaper]{ascelike-new}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

%usepackage{lmodern} % removed in favour of newtxtext and newtxmath

usepackage{graphicx}

usepackage[figurename=Fig.,labelfont=bf,labelsep=period]{caption}

usepackage{subcaption}

usepackage{newtxtext,newtxmath}

%usepackage{mathptmx} % removed because it causes your issue in combination

                       % with newtxmath
